So, right away we can eliminate the term ‘aggression’ when we encounter a cat that shows a ferocious hiss if we come to close. Obviously, one of us is not a cat. But, what does it mean when we are quietly petting our cat and she suddenly turns, grabs the hand that pets her and sinks her teeth into it? Surely, that’s a form of aggression; even if we aren’t members of the same species. Getting away from definitions and such, what we really want to know is why does a cat show what is definitely a behavior that says “get away and don’t touch me!!”, or what many term as cat aggression.
First of all it is helpful to not confuse cat aggression with the kind of aggression that’s found in people. People are complex entities that are driven by many things, such as emotions, belief systems, family ties, the “seven deadly sins”, the boss’s moods or the NFL on Sundays. People are able to pass their aggressive nature around like the common cold infecting those around them, sphynx cat for sale especially when inspired by a call to action for a certain cause (think half-time in the locker room). We can even turn it on and off, if and when we want to. That same Wikipedia definition goes on to state that some psychologists draw a direct relationship between low IQ and aggressive behavior; those towards the higher end of the IQ spectrum are more likely to be termed as assertive. But, our purpose here is not to split hairs between aggressive and assertive human personalities.
In animals the aggressive side of their personality is usually linked to certain and specific situations. Here it is helpful to note the difference between cat aggression and the predatory nature of cats. Certainly, when cats demonstrate the stalking, chasing, capturing and killing of prey they are showing a very distinctive quality of aggression. This type of aggression is called goal oriented aggression. Cats hunt in order to provide food for themselves, and in some cases, their kittens. Even when your cat brings home a field mouse and presents it to you, she is acting out a eons old instinct, although she may not know what to do with her catch. Cats will hunt, quite often for their entire life, while at the same time they are well fed and cared for by their owner. Maybe this is just cats showing they can be assertive, too.
Most all other forms of cat aggression are known as defensive aggression. These kinds of cat aggression characteristics can be directly attributed to three aspects of the nature of cats:
Cats mark (define) their territory with scent marks that tell all others that this is her land. She will defend that territory against all other cats. Notice I say ‘all other cats’. She will confront and chase away all uninvited cats vigorously. Other animals, including people, she may or may not confront, depending on whether she feels threatened. Predators may get a free pass as she lowers her head, with eyes dilated, and becomes as unobtrusive as possible. But other cats will get a very unwelcome confrontation and generally will respect what she is telling them, including avoiding her territory in the future. Or at least, if they have to, they’ll cross her territory very cautiously (isn’t it amazing how swift a cat can be, yet when called for they can move in the slo-motion that TV sports analysts would admire?).
The only invited guests she’ll entertain are any males that respond to her caterwauling when she comes into heat. “Invited” guests may be a little misleading. Complete strangers can show up and the result is a ritual to determine who the best mate is will ensue. This will include fighting and growling in single elimination scraps until a victor is determined. Even then a female cat might mate with the second or third place finisher in addition to the winner. It’s all so very uncivilized and unladylike. But, when she’s mated all those boys had better watch out. They’ll all be chased off so that she can bear her kittens in well deserved peace and solitude.
After the kittens are born, there is even more reason to demonstrate her territorial cat aggression. Not only does she have to protect her territory and the food it supplies, but she has to offer protection to her young brood. Cats have very strong maternal instincts and she will face the fiercest threat to her kittens head-on. And, if the predatory threat is too strong for her, she will distract it into chasing her so she can lead it away from the kittens den.
Cat aggression is also linked to the experiences cats had when they were a kitten. Everything your cat knows, she learned when she was a kitten. When kittens have positive experiences while they are young, the more likely they will accept those encounters when they are grown. If kittens have a bad encounter with unfriendly people or other pets, or their kitten-hood is over-protective and they don’t have the opportunity to have a lot of experiences, they can grow into shy, withdrawn adult cats. This socialization of kittens is the process of allowing them a well-rounded introduction to the things that make up her world. Cats are smart enough to know what poses a danger and what is not a threat. A kitten who was introduced to a friendly dog will grow up not being threatened by dogs in general. But, she will know when a dog isn’t being friendly, she shouldn’t stick around to find out why.
