why do cats bite and scratch when you pet them

Dylan

I love petting my cat, but sometimes out of nowhere, she’ll suddenly bite or scratch me. It’s confusing because one minute she’s purring and enjoying the attention, and the next, she’s lashing out. Is this normal? Why do cats do this, and how can I tell when she’s had enough?

Cats often bite or scratch during petting because they get overstimulated. Their skin is super sensitive, and what starts as pleasant can quickly become overwhelming. Watch for subtle signs like tail flicking or ears flattening—those are hints they’re done with the cuddles.

Some cats have a low tolerance for prolonged touch, especially if they weren’t socialized well as kittens. My rescue cat, Luna, does this too—she loves three pets max, then it’s game over. Try shorter, gentler sessions to see if that helps.

It could also be a form of play aggression. Cats use their mouths and claws to interact with the world, and sometimes they don’t realize they’re hurting you. Redirecting their energy with a toy before petting might reduce the sudden attacks.

I’ve read that certain spots, like the belly or base of the tail, are trigger zones for many cats. My tabby goes from sweet to spicy if I touch near his tail. Stick to safer areas like the head and chin to avoid surprises.
