If you hear an unending succession of growling or hissing, then your cats may be fighting.

For example, if one of the cats yelps out in pain and hisses or growls, then your cats may be engaged in a fight. Usually, when cats play, they alternate biting one another. If one cat is frequently biting another cat who is trying to get away, it is unlikely that they are playing.

If your cats are chasing each other, then the same rule applies. They should both be chasing each other instead of one cat chasing the other the entire time.

Cats that have been playing will act friendly toward each other and resume their normal behavior afterwards. They may even nap or lay down near one another.

You may need to slowly reintroduce the cats to each other to prevent a future fight. It is always helpful to have a baby gate handy to separate your cats. This allows you to reintroduce them and let them interact in ways where they can’t harm each other.

Additionally, one of the cats may see you and re-direct its anger on you. As a result, their behavior toward you may change even after the fight has ended. If your cat bites you, you should go to the hospital or urgent care as soon as possible. Cat bites often get infected with pasteurella strains, and they can also cause cellulitis. Early treatment is the best means or prevention. [13] X Research source

Reward your cats with praise and treats when they interact in a friendly manner.
