Why does my cat bite?

Updated

Short answer

A cat bites when stroking becomes too much, when it hunts your hands or feet in play, or when it is scared or in pain. Play biting can be redirected to toys, while new biting when touched is a sign to have the cat's health checked.

Why it happens

  • Too much stroking

    The cat purrs on your lap and then suddenly bites. Beforehand it nearly always shows signs: the tip of the tail flicks, the ears turn sideways, the skin on its back twitches. It is not spite but a request to stop that we missed.

  • Play as hunting

    A young cat ambushes your feet or pounces on a hand moving under the duvet. It is a hunting game: moving fingers look like prey.

  • Raised without littermates

    A kitten learns to bite gently by playing with its littermates: bite too hard and the game stops. A kitten raised alone or taken away too early missed that lesson, and if people played with it using their hands, it learned that hands are toys.

  • Fear

    A cat that is cornered, held against its will or cannot get away from children defends itself. Before it bites it hisses, flattens its ears and crouches: these are its last warnings.

  • Pain

    If a calm cat has started biting when you touch its back, belly or hips, it may hurt there. That bite is not a change of character but a signal.

What helps

  • Never play with your hands Hands and feet must not be toys. Play with a wand toy, a feather toy or a toy mouse you can throw away from you, so the cat hunts the toy and not your fingers.
  • Daily hunting games Have a few short play sessions a day: let the cat stalk, lie in wait and finally catch the toy. A tired cat that has made its catch goes for feet far less.
  • Shorter stroking Stroke the head, cheeks and chin, briefly, and stop before the cat shows impatience. Let it come and go as it likes.
  • Freeze rather than pull away If the cat has latched on, stop moving and calmly redirect it to a toy. Jerking your hand away makes it grip harder, and shouting or smacking only teaches the cat to fear you.
  • Explain it to children Children need to know that a cat must not be held against its will, chased or woken up. A cat that has somewhere to retreat bites far less.

When to see a trainer or behaviourist

If an adult cat bites hard enough to draw blood, attacks people without warning or bites more and more, first see a vet, then contact a qualified animal behaviourist. In the meantime do not punish the cat, do not stare it in the eye and do not approach it when it is tense: give it space and make sure nobody gets hurt.

When it is a question for a vet

See a vet if the cat has suddenly started biting when you touch a particular part of its body, if it also hides, eats less or no longer jumps, or if an older cat's behaviour has changed. If a cat bite has broken your skin, the wound can become infected, so speak to your own doctor.

These answers explain ordinary behaviour and do not replace advice from a vet or a qualified trainer. If the behaviour changed suddenly, see a vet.
