My cat is doing some weird stuff...?

Does she seem to be angry when she does it?

Because my cat does that too. But he's not angry. I'll be petting him and he'll all of a sudden bite my hands but than go right back to purring.

I searched it up online and I found out that it might be instincts. In the wild many cats usually only have physical contact when they are either fighting or with a mate.

So your cat might be biting you because he's reacting to his instincts when there's physical contact. Animals don't think like us but go off of instincts. So it might just be that.

Otherwise I'd talk to your vet. Might be a tooth ache or something.

I was reading about why cats will sometimes suddenly bite their owners when you try to cuddle with them and it said that cats will do that to show affection. I don't think theres anything wrong but I don't understand why your cat would bite your face >.<

I'd get her checked out by the vet - I know, that's what everyone says! But, sudden changes in behavior can mean something's going on with their bodies. She's a lot older now so you should go find out if something's bothering her healthwise and she hasn't been to the vet in the last 6 months.
