02. Urinating (Spraying) to claim territory

Another obvious attempt to show dominance is by claiming territory. This is typically done by spraying their scent onto an area to claim it. This will mark their scent to keep other submissive cats away.

03. Pushing cats around at feeding time

If you have more than one cat you may have seen one of the cats acting aggressively during mealtime. This can be a show of dominance. However, this could also be food aggression, but that is a topic for another day.

04. Pushing cats away from their water bowl

You should not push your cat for biting your kitten’s bum. If you notice this happening you may want to punish the cat to teach it a lesson. But, it tends to confuse the cat. This can then lead to a defensive attack or a breakdown of trust for you.

Once you lash out at a cat it is not intelligent enough to connect your action to its behavior. Firstly, it may feel it is doing nothing wrong. And, lastly, it may not associate it as punishment for that act even if it did, are you with me?

Can a new kitten affect the hierarchy in your home?

Why is my cat biting her kittens hard?

As long as your cat’s bites are not breaking the skin, then you won’t need to worry. Cats will often chastise a kitten with a quick, sharp bite, that gets their attention but shouldn’t be breaking the skin. If you are worried, check the kitten’s skin in the bitten area, and it should be free of punctures.

If, however, there is blood, then you will need to separate the kitten for their safety and contact your vet, as you may need to wean the kitten yourself if the mom has rejected it and is endangering their safety.

Why does my cat bite my kitten’s legs?

When your cat does this, it is generally an aggressive ‘cue’ for the kitten to hurry up and move away. While the kitten will likely panic and make a big deal out of it, as long as the older cat is not breaking the skin then you shouldn’t need to worry.

Cats communicate in several ways and while a quick, sharp bite or your cat nipping at the heels of the kitten might look a bit scary, as long as they aren’t piercing the skin then it’s best to just let it run its course. Think of it as a ‘cat spanking’ and you’re on the right track for interpreting this behavior.

Can instinct cause a cat to bite another cat’s bum?

Yes, this can be instinctual behavior, and unneutered male cats are usually the worst offenders in this regard when another male cat is in the house.

Typically, one male will try to bite the other bum or testicles as an aggressive show of dominance and experts recommend that you consider neutering the aggressor to calm the cat’s aggression levels down and to put a stop to this behavior.

Females will sometimes do this to males as well, although this is typically not going to be done to the point of actual harm, just to give the male a bit of a scare so that he understands that the female is not to be trifled with.

Why does my cat also bite while grooming?

White kittens playing with their mother.

White kittens playing with their mother.

Biting during grooming is typically done for one of two reasons. The first is that a quick, sharp bite that doesn’t pierce the skin serves as an effective way to tell the other cat ‘stay still while I groom you’. The second most common reason is the removal of parasitic insects such as fleas or lice.

When that’s the case, you will usually see a quick, sharp bite, followed by ‘mowing’, where your cat takes little nips and moves forward a few inches, as if ‘mowing’ a grass lawn in rows.

Neither of these reasons should be a cause for alarm, however, as long as the bites are not causing bleeding or otherwise harming the other cat.

Why do cats bite each other (In general)?

When the biting is not hostile, it may occur for several different reasons. Cats will bite each other as a quick warning, for instance, that the other cat is doing something that is not going to be tolerated.

Cats will also give ‘play bites’ during bouts of wrestling around the house, and while they might look scary or even elicit a vocal response from the other cat, examination of the area will usually show that they weren’t harmed.

Cats will also bite each other or even you as a way to say ‘stop grooming/petting me, I’ve had enough’. Provided that your cat isn’t showing outright aggression signs, such as quick, sharp tail waving, ears bared back, or screeching then it should be fine.

Just leave the cat alone if you were bitten and if it was another cat that got the bite, they should get the message very quickly and leave the temperamental another cat alone.

How do you know if your cat is rejecting her kittens?

The most common thing you will see if a cat is rejecting her kittens is that she will move the kitten away from the rest or, failing this, you will see her pushing the kitten away or otherwise refusing to let it nurse from her.

Kittens need regular feedings to survive, especially in the first week when they must feed every 2 hours, so if you see these behaviors then you should call your vet right away. You will likely need to nurse the kitten with formula if they are to survive.
