why do cats bite when you're petting them

Wyatt

I love petting my cat, but sometimes she suddenly bites me out of nowhere. It's confusing because she seems to enjoy the attention at first, purring and rubbing against me. Why do cats do this? Is it a sign of aggression, or is there another reason behind this behavior?

Luna

Cats often bite during petting due to overstimulation. While they enjoy affection, their tolerance for physical contact has limits. When petting continues past their comfort zone, they may bite as a way to communicate, "That's enough." This is not necessarily aggression but a signal to stop.

Some cats bite during petting as a form of play or redirected energy. If they get overly excited, they might mistake your hand for a toy. Additionally, younger cats or those with high energy levels may not yet have learned to moderate their reactions during interactions.

My cat does this too, but only when I pet her belly. Does that mean she doesn’t like belly rubs?

Santiago Many cats are sensitive about their bellies, as it’s a vulnerable area. Even if they roll over, it doesn’t always mean they want it touched. Your cat’s bite is likely a defensive reaction, not necessarily dislike—just a request for space.

Could it be related to how long I pet my cat? Mine seems fine for a few minutes but then nips.

Dylan Yes, duration matters! Cats have varying thresholds for petting. Pay attention to subtle signs like tail flicking, ear twitching, or skin rippling—these often signal they’re nearing their limit. Shortening petting sessions can prevent overstimulation bites.
