Swollen lip/chin. I'm so worried! What to do?

I'm worried that something had bit her or that she hurt herself. Can anyone help me please ? Thank you

Hmmm...it could be anything from a bite to an ulcer.  I'd get her to the vet for a check over to see what's going on.  BTW, she's a cutie and has a cute little nosie!

It could be acne..does she have any bumps on her chin? They are usually black but can be skin coloured.

There is is also Eosinophilic Granuloma.

Either way..a vet visit is probably in order.

No bumps or anything else there
The chin has gone down now but I'll see a vet just in case! Thank you!

My cat recently started getting this. It comes and goes. He's been checked out by the vet several times and we cannot find anything specific. This last time, however, it has yet to go away, though the swelling has gone down and it does not appear as red and "angry", and I am actually worried that something might be going on in his mouth below the gumline. So definitely get your cat checked and let us know. My guy is going to the vet for something else on Monday, so we'll be getting that looked at - again.
