Why Does My Cat Bite Me?

If you’ve ever been on the receiving end of an angry cat’s teeth sinking into your skin, it makes sense you’d want to ask the question, “Why does my cat bite me?!” Sometimes it’s an aggressive bite that sends you yelping, other times it feels like more of a mild warning bite, and there are even instances where it seems like a gentle love nibble, depending on the cat’s body language.

Below, we discuss all three scenarios and also offer guidance on how to navigate this tricky cat behavior. After you find out why your cat’s biting you, learn why cats lick you.

Why does my cat bite me?

The short answer to “Why does my cat bite me?” is that they’re trying to tell you something. The long answer is a bit more nuanced, but we can break it down into three categories: they’re feeling annoyed or threatened, they’re trying to get your attention, or they’re playing.

“The most common reason a cat bites you is that they aren’t enjoying the current interaction. Biting is their way to say ‘back off’ when they feel threatened [or annoyed],” says Rachel Barrack, DVM, a veterinarian at Animal Acupuncture in New York City. “Cats also may bite when playing, as they are natural predators.”

Deborah S. Greco, DVM, a veterinarian and the senior research scientist for Nestle Purina Petcare, adds that a cat might also bite if they want or need something from you. In that sense, they may use biting as a means of trying to communicate that need. For example, maybe their litter box needs cleaning, they’re craving some playtime, or they’re hungry.

“It’s important to carve time out of your day to play with your cat, to check that their litter box is clean, and to make sure that they have plenty of food and water, to help minimize the biting,” says Dr. Greco.

Do certain behaviors trigger my cat biting me?

As mentioned above, a common reason why cats bite is that they are afraid, angry, or annoyed. “This makes it especially important never to tease your cat, which can be frustrating and threatening,” says Dr. Greco. “Also, if your cat has a medical condition, they may bite because of the pain they’re feeling. Whatever the reason, a cat often gives warning signs before they bite. If she is hissing, flattening her ears, or emitting a low growl, it’s time to back away.”

How common is it for cats to bite?

Generally speaking, it’s pretty common for cats to bite, and there are many reasons why they may suddenly start biting, seemingly unprovoked. It’s important to understand that cat biting isn’t always because of aggressive behavior, but can happen for reasons we outlined above.

Do cats ever “love bite”?

A “love bite” might look like a gentle nibble, or your cat gently holding their teeth on your skin without pressing too hard. This is a much more common behavior between cats, but some cats might also do it to their owners.

“A playful nibble or love bite is very different from a truly aggressive bite that typically is in conjunction with hissing and meant to cause harm,” says Dr. Barrack. Think of it as a really weird cat way to say, “I like you!”
