Managing Aggression in the Multi-Cat Home

Posted on December 17, 2023December 17, 2023 by felinepurrspective_u3q4o6

Cats staring — The direct stare is not a friendly behavior.

It is increasingly common for people to own more than one cat. With more than one cat in the home, conflict between cats of the same household is also increasing.

managing aggression in the multi-cat home

It can be challenging to identify aggressive behavior. Cats play roughly and what looks like play might be a fight in progress. Subtle signs like staring and tail twitching are hard to recognize from across the room – overt behaviors such as chasing, wrestling and vocalizing are more likely to catch our eye and ear and alert us to trouble. [Reference 1]

Things to keep an eye/ear out for:

aggression

vocalizing: growling, hissing, long drawn out meowing
chasing where one cat is the “chaser”
offensive postures: stiffened legs, stiff tail
defensive postures: crouching, tucked head [References 1, 2]

play

Frequent and long-lasting wrestling/chasing
You may hear occasional short, soft meows or chirrups [Reference 2]
Reciprocity – cats take turns being on top or chasing

things in-between

There are interactions that combine both play and aggression but do not result in a fight [Reference 1].

One cat wants to play and the other does not, responding with a swat and hiss to end the play sequence.
Cats of different social groups may need to pass each other. There may be some hissing but body postures are not stiff nor crouching.

interventions – Managing Aggression in the multi-cat home

When you hear yowling/hissing/growling or see stiff or crouching postures, it is time to investigate. Intervention may just consist of opening a door wider so that both cats can pass through. If things are a bit more serious, separate the participants using noise or a barrier. See Managing the Indoor Cat Fight.

It is important to identify the social groups in the house. A few aggressive interactions between cats who sleep snuggled together, groom each other and share resources most likely will not require intervention [Reference 1].

Gus and Marley tolerate each other with the occasional spat.

PLAY can become AGGRESSION

A cat becomes too exuberant and begins to scratch and bite harder.
Reciprocity stops – cats are no longer taking turns.
Hissing, growling increases as the other cat tries to end the play sequence.

Decreasing aggressive play towards other cats

By reducing the desire to play, cats will play less, decreasing the chance that aggressive play happens [Reference 2].

Provide play-time for the whole group at predictable times: scatter toys around the room for the group to interact with; play with the aggressive/energetic cats with a wand toy or other interactive toys.
These more active cats can also benefit from play time away from the other cats in a separate room [Reference 2].

non-play aggression

Play aggression starts with positive, friendly emotions, whereas non-play aggression arises from fear, anxiety, and frustration [Reference 2].

Common scenarios include cats blocking other cats from accessing resources, or trapping another cat in a place that has no escape route. And there are those “bully” cats that “pick on” timid or shy cats, who respond with crouching down and scooting away.

Have plenty of resources spread out through the house (a cat can’t block two places at once).
Have multiple, separated play/resting/observation areas.
Monitor “bottlenecks”: provide places for cats to avoid each other, e.g. a high cat tree near a doorway, offering an escape from another cat passing through.
Enrich the “bully” cat: give him time away from cats not of his social group with access to food puzzles and novel toys.
Enrich the “victim”cat: give him or her time away from the bully and his buddies.
Put a collar with a bell on the “bully” so that other cats know he or she is coming. [Reference 2]

redirected aggression

Something happens that frustrates or frightens a cat, and the cat strikes out at whomever is closest. The cat cannot strike out at the cause of the arousal – it may be out of reach or too risky to confront.

A frequent scenario is a strange cat appearing at a window. The cat indoors cannot engage the stranger and redirects her frustration and anger at another cat nearby. Other triggers include high-pitched or loud noises, unusual odors, or visitors in the house.

Dealing With Redirected Aggression [Reference 2]

Separate the cats and reintroduce gradually.
Desensitize the aggressor cat to whatever stimulated the aggression: if it was a noise – play this sound (or something like it) when the cat is around. Start with a low volume and gradually increase to full volume while offering high value treats.
Visitors in the house: train the cat to go to a safe place when visitors come in.
For more information, see Redirected Aggression in Your Cat – When It Becomes a Problem.

other interventions – managing aggression in the multi-cat home

Medication may be helpful for very timid cats, highly aggressive cats, or to manage redirected aggression where the cat will continue to be exposed to the trigger [Reference 2]. See Dealing with Anxiety and Misbehavior in Your Cat.
If conflict continues, you may need to set up a time-sharing plan and have different social groups use critical areas in shifts. See How Cats Get Along – Timesharing.
Rehoming the aggressor cat with his social group or the victim cat with her social group may be viable alternatives [Reference 2].

Managing aggression in the multi-cat home requires careful observation of how the resident cats interact with each other. Knowledge of the social groups in the home can help in deciding whether intervention is needed. The cat owner must also be willing to respond to problems by adapting the environment, providing opportunities for cognitive enrichment, such as group and individual play time, and separating and reintroducing cats, when necessary.

Managing aggression in the multi-cat home is essential for the health and happiness of the feline and human occupants.

Social Groups of Cats in The Multi-Cat Home

Posted on December 1, 2023December 3, 2023 by felinepurrspective_u3q4o6

Social Groups of cats in the multi-cat home

This post was originally published 8/29/20. This newer version has been edited to incorporate new material and references.

If there is plenty of food around, free-roaming cats tend to form groups called colonies. The core of the cat colony are the females, typically a mother, her sisters, and her daughters. These females share the care of the kittens – they nurse each others’ kittens and even help each other give birth.

Male kittens are driven off by their mothers at maturity to avoid inbreeding. They can become solitary hunters like their wildcat ancestors or become attached to an unrelated colony if accepted by the females.

Smaller social groups of cats often form within the larger social group of the cat colony. These groups of 2 or more cats typically

sleep snuggled together
groom each other
rub against each other
“play fight”.

These cats are comfortable sharing resources: food, water, litter boxes, sleeping and resting places. Often these are cats that grew up together but that is not always the case.

social groups of cats indoors -managing the multi-cat home

In the multi-cat home, some cats also prefer to stay together. Identifying the social groups of cats in the home can aid in allocating resources and reduce conflict among the resident cats [Reference 1].

Identifying the social groups of cats

Members of the same social group may

sleep snuggled together
groom each
rub against each other
engage in mutual social play.

There are no hard and fast rules to affiliation: some cats will not snuggle together, but will groom each other and play together.

A Multi-Cat Household and its Social Groups

There are 3 social groups in this 4 cat household.

Social Group 1

Athena forms her own social group. She is a 15 year old spayed female. She recognizes her housemates but prefers to spend time by herself or with her owners.

Social Group 2

Marley (14 yr neutered male) will hang out with 4 year old Zelda. They will rest together and “share” snacks. They will occasionally “play fight”.

Social Group 3

Zelda and Gus (3 yr old neutered male) groom each other’s heads and play together occasionally.

Gus and Zelda also go on walks together with their owners.

Allocating resources in the multi-cat home to reduce conflict

One of the keys to harmony in the multi-cat home is to provide multiple resources and spread them throughout the house. The goal is to ensure that all cats have access to litter boxes, food and water without having to compete with another cat. Here is a simple diagram showing the location of litter boxes on the second floor of a multi-story home [Reference 1].

When locating resources, watch for “bottlenecks” such hallway doors where cats may have to pass each other. Try and place litter boxes, water stations… away from these areas.

House map cat resources — A simple sketch of your house can help with locating litter boxes.

tips for managing resources in the multi-cat home

# litter boxes = # social groups + 1
Feed cats individually and out of sight of each other.
Have daily play time for each cat
Have multiple sleeping, resting places – have secluded and elevated choices

monitoring interactions between cats to manage conflict

Once the social groups in the house are identified, it important for the cat owner to monitor how the cats are getting along and intervene, if necessary, to prevent conflict [Reference 1].

A cat fight can result in injuries to the fighting cats and the humans who try and manage the fight.
Aggression does not need to cause physical injury – psychological stress resulting from one cat guarding resources from another can result in illness and undesirable behaviors such as house-soiling.

signs of conflict – signs of play

It is important to be aware of potential conflict in the multi-cat home. Signs of conflict not only include chasing, running away, howling and hissing, but also more subtle, seemingly harmless behaviors such as staring and blocking doorways. To make things more confusing, chasing and running away can be play behaviors! For more information, visit “How Do Your Cats Get Along – Conflict Behaviors”.

Cats are socially flexible and can form social groups with unrelated cats, although the strength and intensity of these social bonds can vary. A few aggressive interactions between cats who sleep snuggled together, groom each other and share resources may not point to a deterioration in their relationship [Reference 2]. However, cats whose affiliation is weaker and whose inter-cat interactions are frequently punctuated with hissing and growling may warrant a call to your veterinarian or a cat behaviorist.

The next post will look at identifying aggressive behaviors in more detail and what interventions are available to the cat owner.

The Behavior of Feeding – Why Separate Cats When Feeding

Posted on June 18, 2023July 9, 2023 by felinepurrspective_u3q4o6

Gus eyes Athena’s dinner and prepares to move in.

Solitary hunters, cats will eat or cache their prey after a successful hunt. Mother cats will bring prey back to their kittens to teach them how to hunt and what to eat but cats typically DO NOT SHARE their prey. They will growl when eating to warn other cats off.

In photos taken on the “cat islands” of Japan (called neko shima), cats line up at dishes of food put out by the island residents. There are 11 islands in Japan that have more cats than people on them. There are not enough mice for the cats to eat so residents of the islands provide food for the cats. Feeding times appear to go smoothly on the cat islands with the occasional spat between cats. The island residents do put out food in more than one location so a cat can always move to another feeding station if he gets into a fight over food. Contrast this with our picture of a wild cat, a solitary hunter, munching his mouse in solitude.

Our indoor cats don’t have the option of leaving if they are the target of food aggression. Although cats may appear to get along eating next to another cat or out of the same bowl, cat behavior experts recommend that we separate cats when feeding, preferably out of sight of other cats. (Reference 1)

Why separate cats when feeding?

Cats with more dominant personalities will nose smaller, more timid cats out of the food bowl.
Victim cats may gorge and eat their food quickly, leading to “scarf and barf”.
Victim cats may start to lose weight.
House-soiling issues can start if the “bully” decides the game should extend to resources other than the food bowl.

These behaviors can be subtle. The “thief “at first just sits quietly near the “target” cat and stares at her. The target may stop eating. There may be some fisticuffs as the target tries to keep eating. Eventually the thief just noses the target out of the bowl, and the target cat leaves.

Strategies to separate cats when feeding

Assign each cat his own food station out of sight of the other cats. If you are meal feeding, you can fill each station with a cat’s portion and call each cat to his station as you place them around the house. Collect the feeders in 15-30 minutes as the cats finish their meals. If you like, you can offer the meals in food puzzles, one per cat.

Locations of feeding stations

You may be able to take advantage of your cat’s preferences when deciding where to locate her feeding station. Some cats like to be up high and can be fed on their cat tree or tops of shelving units.

Closets can also make good feeding stations. Cats who like to be up high can eat on the top shelf and may just need a step ladder, storage cubes that form a ladder, or a single pole cat tree to get up there. If you just need to keep the family dog out, a gadget called a “Door Buddy” can work.

Baby gates can be used to block off doors to closets or rooms to separate cats. Although an agile, determined cat can easily scale a baby gate, this is usually pretty difficult for a dog.

feeding stations

Microchip Feeders

If you are dealing with cats on different diets or cats that eat slowly or “graze”, microchip feeders such as the SureFeed Microchip Pet Feeder are worth the cost. These feeders will only open for the cat or cats they are programmed for.

Enclosures for Feeding

A “Meow Space” is a deluxe feeding enclosure. It is ventilated and has a locking pet door which can be accessed by microchip or collar tag. Like a microchip feeder, the “Meow Space” will only open for the cat or cats it is programmed for.

A plastic pet carrier can make a great “kitty diner”. Each cat can eat in his own carrier. If one cat finishes before another, the gate can be closed until the slower eater is done. This also helps your cat become more comfortable with his/her carrier.

Tip: Make a carrier cover that will “camouflage” the carrier, matching your color scheme and decor.

not enough room to separate cats when feeding?

Consider feeding social groups together. Cats who belong to the same social group prefer to spend time with each other and are often willing to share resources such as food and litter boxes.

How do you know if cats are affiliated? The following behaviors can help you identify the social groups in your home.

Sleeping the same room
Allogrooming (grooming each other)
Sleeping touching each other
Touching noses

Note who does what and with whom, then diagram the social groups in your house. You may be able to feed cats in a social group in the same area. It is still recommended for each cat to have a separate bowl, be spaced apart, and to meal feed the kitties.

Separating your cat from other animals while eating allows your cat to feed in the same way as a wild cat. Feeding alone helps avoid behaviors like gorging and vomiting which can affect a cat’s physical and mental health. Although it can be a challenge to separate cats when feeding, attention to each cat’s preferences and identifying the social groups in your home can help you develop a feeding strategy.

How Cats Get Along with Other Species

Posted on December 18, 2022 by felinepurrspective_u3q4o6

In this post, we look at how cats get along with other species – are their behaviors affiliative or is there conflict?

How cats get along with other species

How Cats Get Along with People: Signs of Affiliation

In an interview with Terry Gross of the NPR show, “Fresh Air”, the well-known anthrozoologist, John Bradshaw, noted that cats view their owners as cats, specifically cats they are affiliated or friendly with. Cats greet us as they would an affiliated cat, rubbing up against us, touching their noses to our hands, licking our hands and faces, snuggling next to us in bed at night.

Cats use the same friendly behaviors when interacting with people as they do with other cats.

nearness
rubbing up a person’s legs (allorubbing)
bunting against our hands (nose touching)
licking hands (allogrooming)
approaching with tail up

How Cats Get along with people: Signs of Conflict

Cats show similar conflict behaviors when interacting with humans that they would use with other cats.

staring
stalking and pouncing
running away
biting, swatting and swiping
arched back and hair standing on end

Young cats in particular can be guilty of stalking and pouncing on owners as they round a corner in the house. Some of these behaviors can be the result of playing with the cat inappropriately or redirected aggression, where the cat associates the owner with a fearful experience.

A petting session sometimes comes to an end when the cat bites or swats the person petting him, then jumps down and runs away. It is important to add to the list above some “pre-conflict” behaviors that we must watch for:

flattened ears
fur on the cat’s back ripples
the cat turns to face you with a stare

How Cats Get along with Children

Cats showed no preference to gender or age when meeting volunteers in a shelter for the first time. The volunteers did not interact with the cats but instead read an age-appropriate book. [Turner, The Mechanics of Social Interactions Between Cats and Their Owners]

After 5 minutes, the volunteers were allowed to interact as they pleased with the cats. The cats reacted strongly to the differences in behavior between men, women and children. Women and girls tended to move onto the floor with the cat and speak quietly; men remained seated, and boys approached the cats immediately, causing them to run away. [See below Turner].

Children, being more active, and less attentive to the body language of cats, tend to elicit more conflict behaviors from cats then adults. Children playing with cats must be supervised by adults as young children, in an excess of enthusiasm, may hit the cat with a toy or chase them.

A cat’s impulse is to flee when chased by a child but if cornered, he may bite or scratch. It is important to allow cats avenues to escape the attention of boisterous youngsters – high cat trees or closets with latches that allow the cat access but not the child.

How Cats Get Along: Cats and Dogs

Although cartoons and films may show cats and dogs as mortal enemies, many co-exist peacefully in human homes.

A recent survey based study by Thomsen et al. (cited below), indicated that the success of the relationship depends on the age of the cat (preferably around 6 months) when introduced to the dog. Ideally, good experiences with friendly, well-behaved dogs during the cat’s “sensitive” period will predispose the cat to forming relationships with dogs. Slow, gradual introductions between cat and dog (similar to Introducing Cats) have the best chance at success

Just like with humans, cats tend to show the same behaviors to dogs they are friendly with that they would show to other cats.

sleep in the same room as the dog, sometimes touching
rub against the dog when greeting
approach with tail up

Although a dog may be affiliated with the cat in his house, this does not mean he will not chase or bark at a strange cat. A cat who has been raised with dogs may still turn and flee from dogs he does not know. Affiliation exists between individual animals, not a whole species.

Dogs also have a set of affiliative behaviors. The hallmarks of a well-socialized dog include:

relaxed body
rapid tail wag
no staring
indirect approach, looking and sniffing at the ground

Canine conflict behaviors include:

backing away or trying to escape
submissive behaviors: flattened ears, tail tucked, looking away
staring, growling, snapping, erect posture
tail held vertically or arched over the back

Another survey-based study (Menchetti et al. cited below) compared owners’ perceptions of how dogs and cats living in their homes get along. Owners felt that:

Dogs are more social than cats towards strange animals and humans
Dogs are more playful than cats with their owners
More dogs lick the cat than vice versa
More cats ignore the dog than vice versa
Most dogs and cats in the same household will sleep together and play together at least occasionally
Although cats and dogs have different body languages, they still manage to understand each other

A Tale of Tails

Both cats and dogs use their tails to communicate.

	Cats	Dogs
Friendly Gesture	Tail up	Tail wagging
Conflict	Tail twitching	Tail up

Somehow, cat-dog pairs translate each other’s language. The cat approaches the dog for a nose-to-nose greeting with tail up and lies down beside him. The dog recognizes the cat’s behaviors as positive signals and he wags his tail.

When the dog approaches the cat with the tail up, the cat recognizes the conflict/aggressive signal, arches his back, twitches his tail and backs slowly away.

Cats will use the same visual signals that they use with other cats when interacting with other species, such as humans and dogs. It is important that we, as pet guardians, know and understand the affiliative and conflict behaviors of each species residing in our homes to prevent altercations and promote peaceful coexistence.

Purrsonality and How Cats Get Along

Posted on December 4, 2022 by felinepurrspective_u3q4o6

Do cats have personalities? If you define personality as “the characteristic sets of behaviors, cognitions, and emotional patterns that are formed from biological and environmental factors, and which change over time” – yes, cats and other animals have personalities. How do describe your cat’s personality? How does personality affect how cats get along?

Studies (see Litchfield et al., cited below) of captive wild cats such as Scottish wild cats and cheetahs have suggested using personality assessments

to house socially compatible animals together
to tailor the environment to an individual animal’s needs – for example, provide more hiding places for a fearful cheetah

Can personality assessment improve the welfare of our domestic cats?

In 2017, Carla Litchfield and her research team published a study on personalities in pet cats. Litchfield’s team conducted a survey of 2,082 cats in New Zealand and Australia. The survey consisted of 52 personality items. Statistical analysis of the data found five reliable personality traits – “The Feline Five”: (citation below)

Neuroticism
Extraversion
Dominance
Impulsiveness
Agreeableness

“The Feline Five” is similar to the Five Factor Method (FFM) used in human personality research. The FFM describes a person’s personality using five factors. An individual’s personality will have varying amounts of each factor. These five factors are: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience.

THE FELINE FIVE AND HOW CATS GET ALONG

Anxious or calm? (neuroticism)

Cats that score high on this factor are typically shy, fearful of people, insecure and anxious. On the other hand, calm cats don’t get as stressed when faced with changes in environment and exposure to other animals and people.

It is worth observing how the anxious cat gets along with other cats in the household. Timid, anxious cats can become the targets of more dominant cats who may stalk and chase them and prevent them from accessing resources such as food and litter boxes.

Providing more resources and hiding areas will improve the welfare of anxious cats.
It may be necessary to provide dedicated areas that only these cats can access.

The anxious cat will also benefit from consistent and regular interaction with humans following the CAT guidelines (See Touch not the cat: interacting with cats).

extroverted or introverted?

Extroverted cats are out-going and inclined to interact with people and other pets. They are sociable and curious. Introverted cats spend more time alone and are more quiet and reserved.

Extroverted cats can be energetic and prone to boredom. This can result in interact conflict – for example, a younger active cat may pick on a senior cat for entertainment. Extroverted cats can benefit from more play (hunting), foraging (food puzzles), and supervised outdoor access via leash walks or a catio.

dominant or Meek?

The dominant cat will stalk and chase other cats and sometimes humans. They displace other pets from favored positions and will steal their food. “Meek” cats are more tolerant of other cats and are willing to time-share places; they don’t exhibit the bullying behavior of a dominant cat.

Dominance behaviors are thought to occur more frequently in captive populations of cats. In the colonies of wild cats, the females raise the kittens co-operatively. There is competition between some male cats but there are also the “family toms”, unrelated male cats that affiliate themselves with the colony and have been known to protect and participate in rearing the kittens. [I. Rochlitz(ed.), The Welfare of Cats, 1-22 © 2007 Springer]

The popular “pack hierarchy” theory of wolves has been abandoned. Observation of non-captive populations of wolves show that they group together in family units, where the parents guide the activities of the group.

In the instance of a dominant cat “bullying” a more timid cat, the welfare of both the bully and the victim must be considered.

Enrich the “bully” – give him or her more opportunities to play (hunt) and forage (food puzzles). If possible, offer supervised outdoor access via leash walks or a catio
Provide the victim with ready access to resources and safe places. This may require separation when the two cats are not supervised.

impulsive or cautious?

Impulsive cats tend to be unpredictable and may react differently to the same thing at different times. Cautious cats are not so easily stimulated by their environment and keep to a smaller set of activities that they are comfortable with. Impulsive behavior is thought to be a response to environmental stress. [Litchfield et. al]

Agreeable or unfriendly?

Agreeable cats are well-adjusted cats that are friendly toward people and other pets. Low scores of agreeableness (irritable, aggressive toward people) may be due to poor socialization, frustration, pain or illness. [Litchfield et al.]

The agreeable cat is thought to be a source of enrichment for other cats in the household.

Personality and How Cats Get Along

Recognizing different personalities in our cats can help us manage how cats get along in our multi-cat homes. Whereas two timid/shy cats may get along, two dominant cats can clash. A dominant cat and timid cat may suffer from a bully-victim relationship.

How Do Your Cats Get Along – Conflict Behaviors

Posted on November 27, 2022 by felinepurrspective_u3q4o6

If your cats get along well, they will share sleeping areas, engage in some allogrooming, and greet each other on occasion by touching noses. Well, you say, my cats aren’t very good friends but they aren’t trying to kill each other, either. What are the signs of conflict? What should we look for to avoid getting to the point “they want to kill each other”?

The 2020 survey referred to in last week’s post not only assessed affiliative behaviors, they also polled respondents on conflict behaviors. They chose seven behaviors associated with conflict. These are listed below with the frequency reported by the participants of the survey. (Elzerman AL, DePorter TL, Beck A, Collin JF. Conflict and affiliative behavior frequency between cats in multi-cat households: a survey-based study. J Feline Med Surg. 2020 Aug;22(8):705-717. doi: 10.1177/1098612X19877988)

Behavior	Frequency	Rank
Stare	daily	7 – Most frequent
Stalking	daily	6
Chasing	daily	5
Running away	weekly	4
Twitching Tail	weekly	3
Hissing	monthly to never	2
Wail/Scream	monthly to never	1 – Least frequent

How do your Cats Get Along?

Let’s take a closer look at these conflict behaviors.

THE STARE

A cat will stare without blinking:

at prey while hunting – he is aware of where that animal is and what it is doing, otherwise he may miss out on dinner!
during a cat fight. Fighting cats must be able to rapidly respond if the other launches an attack.
to discourage another cat from accessing a resource.

Cat blocking other cat — Zelda looks innocent but she is keeping another cat from going through the door.

If you see one of your cats fixing an unblinking stare on another, take note of the circumstances and see what happens if you intervene. For example, if one cat is staring at another cat and is sitting in a doorway, she may be blocking the other from resources through that doorway.

Interrupt the stare by opening the door wider, throwing a treat away from the doorway, or redirecting the “door-blocker” with a toy. Does this give the other cat a chance to get through the doorway? If this is successful, you may want to look more closely at how these two cats get along.

Avoid handling the cats in this situation in case they are more aroused than they appear.

Stalking, Chasing and Running Away

These behaviors may be associated with:

hunting
fighting
cats playing together

When hunting, the cat is targeting a toy or prey. It is object play. But how do we know whether two cats are fighting or playing? After all, many of the same moves in a cat fight are seen when cats play together.

Just like a football game, play between cats has distinct rules. And, like football, tempers may flare when a player challenges the rules. What starts as play can escalate into a cat fight.

invitation to play

play sequence

end of play

Are these cats playing?

Social play consists of an invitation to play, the play sequence, and the end of play. The rules are:

Claws are not extended
Biting is gentle without intent to injure
The invitation to play is often repeated by one or the other of the cats throughout the interaction.
If one cat declines play (there may be some hissing and growling here), the game ends.

If you see that the “rules” are not being followed, it is time to shake a bag of treats or can of coins and redirect or separate the participants. [see Managing the Indoor Cat Fight].

Check all your cats regularly for wounds from bites and scratches. If you notice your cats having a lot of wounds from scratches or bites and they “play” together, this may not be play. It may be conflict and it is time to observe the cats, assess their environment and social status.

Twitching Tail

A twitching tail indicates that a cat is focusing on something. The tail is for balance and changing direction – the tail often twitches before the cat pounces.

The twitching tail + stare > pounce: Is this play? conflict?
Are the rules of play being followed?
A map of the social groups in the house can help with deciding whether this is play or conflict.

Vocalizations – Hissing

The hiss is that snake-like sound. Cats may hiss when they are:

afraid
startled
frustrated
displeased
You will hear it in a cat fight, often from the cat on the defensive.

Vocalizations – Wailing/Screaming

Cats will wail or scream:

if they are fearful
if they are hurt and in pain
if they are fighting

You must decide from the circumstances and the body language of the cat or cats if these vocalizations are meaningful. If it is a cat fight, the combatants must be separated [managing the indoor cat fight]; if a cat is hurt, you must get the cat in a box or carrier for a trip to the vet.

Don’t wait for a fight to break out. Take a few moments to determine if your cats get along and if there is anything you can do to improve things.

Map social groups [Social Groups of Cats]
Draw a house map of resources (litter boxes, food stations, water, scratchers). Draw paths showing how cats reach these resources.
Move furniture if necessary to make accessing resources easier for all cats.
Make sure there sufficient resources for the number of cats.

Next week, we’ll take a look at describing individual cats’ personalities. How does this affect how cats get along?

How Do Your Cats Get Along? Affiliative Behaviors

Posted on November 20, 2022June 16, 2023 by felinepurrspective_u3q4o6

Affiliated cats — Gus and Zelda are not a bonded pair but do groom each other.

Have more than one cat? How do your cats get along? Are they “bonded” or affiliated?

If there is a reliable source of food, free-roaming cats will often form groups called colonies. Within the colony, there are smaller groups of 2 or more cats that prefer to spend time together. These cats are comfortable sharing resources such as food, water, latrine areas, sleeping and resting places. Some refer to these cats as “preferred associates”; others call them bonded or affiliated.

This post is the first in a 3 part series of “How do your cats get along?”: 1) signs of affiliation 2) signs of conflict 3) personalities in the multi-cat home.

“Preferred associates” show affiliative behaviors. You may find them:

snuggled up taking a nap
rubbing against each other when greeting
grooming each other
“play” fighting
twining their tails together

Not all cats have preferred associates. Within the cat colony may be “groups” of just one cat, who keeps to herself but shares the colony territory and resources. So, not only is there the strong bond of the preferred associates, there is also the looser affiliation of the members of the cat colony.

Multi-cat homes host ad hoc cat colonies. When I am taking a history for a veterinary exam, I usually ask guardians with more than one pet how their cats get along. The big three questions for multi-cat homes are:

Do your cats sleep touching each other?
Do they play together, with claws sheathed and taking turns?
Do they groom each other?

These 3 questions barely scrape the surface of how cats get along and whether or not there is potential for conflict or ongoing conflict in the home. Like human social relationships, relationships among cats can be complex.

A survey of 2492 multi-cat households published in 2020* set out to see if there was a relationship between household factors (type of house, number of litter boxes, feeding stations, scratching posts), and how often affiliative and conflict behaviors were seen.

*Elzerman AL, DePorter TL, Beck A, Collin JF. Conflict and affiliative behavior frequency between cats in multi-cat households: a survey-based study. J Feline Med Surg. 2020 Aug;22(8):705-717. doi: 10.1177/1098612X19877988.

Affiliative behaviors in cats – from most frequent to least frequent

sleeping in the same room

Cats don’t have to be “preferred associates” to choose a spot in the sun in the same room as a housemate cat. As long as there is plenty of space, peaceful coexistence should be possible.

Most frequently seen affiliative behavior – multiple times a day

allogrooming

Allogrooming refers to a cat grooming another cat by licking around the head or ears. It occurs most frequently among cats that are related…BUT … it is not restricted to family groups. It can be a way for cats to redirect potential aggression. A few quick licks to the head can soothe a would-be combatant, avoiding a fight. Sometimes, you will see cats who are not particularly chummy grooming each other’s head or neck.

Frequency – several times a day

Sleeping Touching each other

I view sleeping snuggled together something bonded cats do whereas the casual touch of cats napping next to each other indicates a weaker affiliation.

Frequency- several times a day

Touching noses

Kittens at Kndergarten — Kittens at “kitten kindergarten” session

Colony cats touch noses when returning from foraging or hunting. Each colony has its signature scent that helps the members of the colony identify each other. House cats being inside all the time may not need to engage in this identifying behavior as much as their outdoor counterparts. However, a cat who has been to the veterinary hospital may not smell quite right to his housemates and peaceful coexistence can be disrupted.

Frequency – once a day

Why isn’t play in the list of affiliative behaviors?
Play between cats incorporates more than one basic behavior. Because social play between cats is “play fighting” and can easily escalate into a fight, behaviors like chasing and stalking are often categorized as conflict behaviors. (See cats at play: a guide to mutual social play)

There are many other things that cats do that may be “affiliative” – tail-twining and rubbing up against each other – that were not included in the study above. However, this basic list can give you an idea of whether harmony reigns in your cat kingdom. Pay attention to how your cats get along and to their body language when interacting.

Next week, we will take a look at “conflict” behaviors and how frequent the survey found them to be.

Dealing with Anxiety and Misbehavior in Your Cat

Posted on August 21, 2022 by felinepurrspective_u3q4o6

Sometimes when your cat behaves “badly”, you are able to address what triggers the misbehavior and life goes back to “normal”: you add a new litter box and the house-soiling stops; you start taking your “bully” cat for walks on a leash and everyone settles back down again. Problem solved!

Other times, you feel you’ve taken care of what triggers the misbehavior but your cat continues to, say, pee in the bathtub. And in still other instances, you can’t eliminate the stressors triggering the behavior, and the behavior persists. For example, you just don’t have the finances to get a bigger house but you don’t want to re-home any of the cats.

Anxiety and misbehavior in your cat

When your cat is stressed, he can become anxious and fearful. Anxiety is a normal reaction to stress and helps the cat respond to perceived danger. One way your cat may let you know she is anxious and fearful, is by “misbehaving”. She may avoid her litter box and or hide and strike out at you when you try to pick her up.

Your vet might recommend a behavior modification plan and an anxiolytic (anti-anxiety) medication to deal with the anxiety and misbehavior in your cat. Behavior modification aims to give the cat a way to cope with the stress that is giving rise to the “misbehavior”. Anxiolytics reduce your cat’s anxiety and put him in a positive emotional state, making him more receptive to behavior modification.

Fluoxetine: Rx for anxiety

Let’s take a look at Fluoxetine, a medication that is frequently prescribed by veterinarians to treat anxiety.

In human circles, fluoxetine is more commonly known by the brand name Prozac. It is a “selective serotonin re-uptake inhibitor” (SSRI).
Serotonin is a neurotransmitter, a chemical that carries “messages” between neurons. Neurotransmitters are typically reabsorbed in the neuron once the “messaging” is done but SSRI’s keep serotonin from being reabsorbed, resulting in more serotonin being available to carry messages between neurons. Serotonin is thought to regulate mood, digestion, and sleep among other metabolic processes (see SSRIs mayoclinic.org).

Your cat should be calmer and less anxious when taking fluoxetine.

House-soiling and aggression toward people are two of the more common behavioral problems in cats. Let’s take a quick look at two cases where fluoxetine and behavior modification helped manage feline anxiety and misbehavior.

Susie, a 13 year old female cat

Problem Behavior: House-soiling in variety of locations with chronic diarrhea

When Susie was 11 years old, her feline house-mate passed away and her owner adopted a younger cat. Susie began pooping outside the box. After most of a year, the owner felt the cats got along OK but house-soiling and diarrhea continued. The owner found Susie “aloof” and difficult to handle. Susie was surrendered to a veterinary clinic when she was 13 years old.

A Plan for Susie

Medical plan: treat the diarrhea

Behavioral plan:

Desensitize Susie to interacting with people
Gradually introduce Susie to the other cats in the clinic

Susie’s Timeline:

Susie is surrendered to the vet clinic in mid-May 2021. She is fearful and reluctant to interact with people and other cats and is placed in a “room of her own”.
In early July, Susie begins taking a steroid medication and also starts fluoxetine. The diarrhea starts to resolve in the next few weeks.
By early September, Susie is becoming less fearful and is interested in coming out of her room. She starts to accept being handled by the clinic staff. She is not pooping outside the litter box as much.
In November, Susie starts having supervised visitations with staff and other cats outside her room.
By next March, Susie is able to be out unsupervised in the clinic during working hours. House-soiling is better – she poops right next to the litter box and not in random locations.

Susie had a long history of house-soiling. Treatment of her medical problem and reducing her anxiety has improved her quality of life. She remains on a low dose of fluoxetine which helps her cope with the stress of interacting with strange people and cats that come to the vet clinic.

Gus, 3 year old male feral cat

Problem Behavior: Aggression toward people

Gus was an intact male cat that was trapped in a live trap. He is positive for Feline Immunodeficiency Virus and was not eligible to be released after being neutered.

Behavior modification plan for Gus:

Desensitization to people
Clicker training for appropriate social behaviors toward people

Gus’s Timeline:

Early March 2019: Gus is trapped with a live trap
March 5: Gus is neutered. Gus is fearful, fighting and biting when handled.
Late March: Gus starts taking fluoxetine, to reduce anxiety and misbehavior. He takes the daily fluoxetine tablet in a treat. At first the drug makes him sleepy but this passes in a few weeks and he is exposed to a variety of people.
Clicker and leash training begin in early June. He learns simple commands to sit, follow a target on a stick, wear a harness and allow humans to pick him up.
Gus is adopted in early August. Owner continues clicker training and outdoor walks.
Gus is weaned off fluoxetine by the end of November, after 7 months of drug therapy. He tolerates people and no longer tries to bite them.

Anxiolytics combined with behavior modification can help you deal with anxiety and misbehavior in your cat. In some cases, a cat can be weaned off the medication while in others, continuing to give a low dose helps when the stressors causing the misbehavior cannot be eliminated.

When Your Cat Thinks Outside the Box: Part 3

Posted on August 14, 2022April 1, 2024 by felinepurrspective_u3q4o6

When your cat thinks outside the box, it may be due to medical, environmental or social issues or a combination of these. In the two previous posts, we considered some of the medical and environmental issues that can give rise to house-soiling. When your cat thinks outside the box, we must also consider his social environment: are his interactions with people and other pets positive?

When your cat thinks outside the box: the social environment

People and pets other than cats

Positive and predictable interactions with people are a key element of a healthy feline environment. Our cats should expect that we will:

allow them to choose whether or not to interact with us
pay attention to their body language
handle them in a way they accept

Following these simple guidelines can help reduce a cat’s anxiety and insecurity. Making your cat feel secure and confident can go a long way to avoiding house-soiling problems.

Do ask family and visitors to follow the CAT guidelines .

Do not punish your cat for house-soiling even if you catch him in the act. Most likely, he or she will not make the connection. Punishment will only increase his or her stress and may increase the motivation to pee or poop in less obvious places (ISFM House-Soiling Guidelines). Punishment may also cause your cat to be afraid of you.

Do consider restricting children and dogs from the litter box areas using baby gates and gadgets such as a “door buddy“.

Be proactive and try to anticipate how your cat will handle new situations: For example, if you are going to have house guests, think how your cat will react to these strangers. Say you have a litter box in the guest bath – you may want to close your cat away from that area when guests are visiting in your home and provide a litter box elsewhere.

dealing with Inter-cat issues

CATS OUTSIDE THE HOME

Neighborhood cats coming into your yard can impact your cat’s behavior. These cats may mark your doors or yard with urine

They may come to the windows and look in. In response, your cat may mark or soil near the doors and windows that lead to the outside. Cat doors may trigger a similar response.

In the previous post, When your cat thinks outside the box: the environment, we talked about noting house-soiling incidents on a map of your house.

If the “x’s” on your house map are near outside doors and windows, neighborhood cats may be a problem. (House-Soiling Guidelines)

Taking Action: Secure Your Cat’s Territory!

Move your cat’s food and water stations away from doors and windows
If necessary, block your cat’s view of the outside by using window film, cardboard, paint… so he cannot see the intruder.
If you see outdoor cats in your yard, consider a motion activated sprinkler or critter spikes (for fences) to discourage the neighborhood cats from coming into your yard.

CATS INSIDE THE HOME

Where are the “x’s” on the housemap?

If the “x’s” are in hallways, stairways, doorways leading into rooms (in the interior of the house), your problem may be coming from inside the house – other cats. (House-Soiling Guidelines)

Cats are socially flexible. They do very well on their own but can live with other cats if there are enough resources and if these are spread out.

Diagram social groups cats — There are 3 social groups in this 4 cat household.

Social Groups of Cats

Within a cat colony, there are often smaller groups of 2 or more cats that prefer to spend time together. These cats will often:

sleep together touching each other
groom each other
rub against each other
“play fight”

These social groups are comfortable sharing resources: food, water, litter boxes, sleeping and resting places. (See Social Groups of Cats)

Most of the time, things go smoothly and different social groups will take turns using the resources. However, occasionally a cat or cats will “pick on” a particular cat. In a wild setting, this cat could move on, joining another colony or living a solitary life. These options are not available to the indoor cat.

Is your house-soiling cat being picked on by another cat? Does your other cat:

stalk and track the house-soiling cat?
stare directly at her?
attack him? (do not mistake aggression for play: see Cats at Play)
block her from using critical resources – litter boxes, food, sleeping places?

The house-soiling cat may feel safest on the owner’s bed and use the bed as a litter box.

What to do:

Diagram the social groups in your multi-cat household using the criteria above.
Note on the house map where different social groups hang out.
Draw the paths cats have to follow to reach food, water and litter boxes.
Which social group does your house-soiling cat belong to?
Does he or she have an open path to reach the litter box? Can a “bully cat” hide behind furniture and ambush him or her?

Taking Action – Make the house-soiling cat feel confident and secure again

Separate the different social groups. Make sure that each group has all their resources (food, water, litter boxes, cat trees).
Set up a time-sharing scheme for different social groups to use the common areas while you are resolving the problem.
Make sure that there are enough resources so that cats of different social groups do not have to share.
Move furniture if necessary to eliminate ambush spots in the litter box areas and on the way to the litter boxes.
Your vet may prescribe medication for the cats involved.

Taking Action: keep the “bully” cat busy and reduce boredom

food puzzles
regular play time
outdoor access on a leash

Once your house-soiling cat is using his or her box again, you can consider gradually reintroducing him or her to the other cats (see Introducing Cats). If he or she is the victim of a “bully”, be sure to go slowly and supervise the interactions between the bully and victim. This may not be successful and cats may need to remain separated or be re-homed.

This is the final part of “when your cat thinks outside the box”. These three posts only scratch the surface of a complex behavior that can be due to medical, environmental or social issues or a combination of these. Your first resource should be your veterinarian. Do consider making a house map and, if you have a multi-cat household, a social diagram. These simple tools can provide you and your vet insight into why your cat thinks outside the box.

Coat Color and Temperament in Cats

Posted on July 3, 2022July 3, 2022 by felinepurrspective_u3q4o6

Does the color of your cat’s coat mean anything? Is there a link between coat color and temperament in cats?

Black cats are often associated with the occult; orange cats tend to be regarded as friendly. Calico and tortoiseshell cats – those cats with tri-colored coats – are considered strong-willed and difficult to work with. There is even a term – “tortitude” – to describe these cats!

In a study published in 2016, researchers at UC Davis decided to look into whether there is a link between coat color and temperament – in particular, do cats with particular colors of coats tend to be more aggressive? Cat owners were recruited online to fill out a survey about their cats. The team received 1,274 responses that they analyzed with statistics.

Owners scored their cats for

aggression toward humans
aggression when being punished, petted, or brushed
aggression when in the veterinary clinic

Aggression toward humans scored the frequency with which a cat reacted with aggressive or affiliative behavior to people. A 6 point scale was used ranging from 0 = never through monthly, weekly, up to 5 = daily. Behaviors included hiss, bite, slap/scratch, bite/scratch and stalk (play), groom/lick, curl up next to, approach and greet with head/body rubs. The possible range of scores was 0-20.

Aggression from handling scored the likelihood that the cat would react to being punished, petted or brushed by hissing, biting, slapping or scratching. Scores ranged from 0 = unlikely to 3 = very likely. The maximum score possible was 27. Aggression during the veterinary visit was also scored from 0 = likely to 3 = very likely but with a maximum score of 9.

Overall, the aggression scores are rather low in all three categories. For example, in the “human aggression” category, high scores were 2-3 out of 20. Female cats had higher scores overall but the research team felt the difference to be small enough that they could combine the sexes in the overall study.

Coat color and temperament – findings

Tortitude

The calico and tortoiseshell cats were found to have some of the higher scores (2.47) for aggression toward humans (Gray and white cats scored 2.26 – so not much different than the tri-color cats).

These scores are not very high scores out of a possible 20.
Calico/tortoiseshell cats are predominantly female (the tri-color pattern is linked to the X chromosome making the combination of 3 colors very rare in male cats). Female cats were found to be a little more aggressive than male cats in this study and this sample would have had more females.
Perhaps, the stereotype of the “strong-willed” tri-colored female cat affected how respondents scored their cats.

other findings

Gray and white cats, both female and male, were more aggressive toward humans and when being handled.
Black and white male cats scored higher than other groups of male cats in human-directed aggression.
Surprisingly, there were no significant differences in aggression among cats at the veterinary clinic.

Although the results of this study seem to support the stereotypes of cat color and aggressive behavior, e. g. “tortitude”, it is best to take these results with a grain of salt.

Overall, the scores for aggression to humans and when being handled were quite low.
The questionnaires were completed by the owners and there will be some differences in the way people interpret and score things.
Stereotypes may have affected how respondents view their cats and scored them.
The questionnaires did not involve a random sample of cats and cat owners but cat owners who voluntarily signed up to fill out the forms. These could be potentially more interested and “saavy” owners.
There will be differences in how people approach and handle their cats.

At the Battersea Dogs and Cats home, cats were more friendly with humans after the human volunteers watched a video demonstrating how to interact with cats. ( see “Practical Guidelines for Interacting with Cats” )

The link between coat color and aggressive behavior does not seem particularly strong. Such information could be useful to cat owners, shelters, and veterinary clinics to allow them to anticipate what behaviors they may encounter. But as the saying goes, “Don’t judge a book by its cover”. A cat’s coat color is only part of the story – it is important to assess each cat as an individual. Approach him or her respectfully following the CAT guidelines.
