Some Reasons Why Cats Bite

Is your cat sick or hurt?

Any sudden changes in habits or behavior are often an indication that your cat has an illness, injury or some other source of discomfort. Cats instinctively hide any signs of being sick or in pain. Cat showing signs of aggression flattened ears, and razor sharp teeth. Angry looking cats are often just scared cats. When afraid, they can act as we do – fight or flight. Cats, if given the chance, would rather run off than stay and fight. Create space between you and your cat. Make it easy for your cat to leave. Move away and clear a big path so your cat can leave the scene.

Redirected aggression:

People do this too, probably a lot more often than cats. Simply put, your cat cannot direct his aggression (defensive, territorial or other) to the target or trigger. So, instead, he lashes out at innocent bystanders – people or other animals. Maybe he or she saw or heard – what it considers to be – threatening gestures or sounds.

Repeated aggressive cat behavior:

Cats can make secret associations with a triggering event such as a certain scent, a resemblance to a person or thing … which could catapult your cat back to another scary space and time that it remembers and the aggressive behavior, will suddenly be repeated.

Defending their territory from other animals:

By nature, even domestic cats are territorial – whether their territory is a favorite chair or a large outdoor area. A cat’s instinct will kick in. In the wild, survival depends on the ability to defend hunting grounds, to feed and protect their young.

Do take your cat to the vet to eliminate any medical causes for the aggressive behavior. Your vet may prescribe mood stabilizers and/or refer you to an animal behaviorist. Both can be very helpful.


  • Know the warning signs (that includes family and guests)
  • Don’t hit or punish your cat. Cats do not understand the concept of punishment. They only know that you are treating them badly and they don’t know why. The end result will be a fearful animal, who will display further aggressive behavior, and justifiably so. It’s a lose – lose situation, and most importantly, love your cat and it will love you back.
