red spot on chin/lip

I thought her tongue was hanging out but after looking closer, it's a big, red pimple type thing. It's just outside her bottom lip. She's eating right now, so I don't think it's bothering her too much. Any ideas?

thanks!

It may be an ulcer. My cat Mickey is getting over calicivirus which caused him to have an ulcer on his tounge and fever. Are there any other symptoms?

No behavior change at all. Her appetite is fine, just scarfed up a bowl of canned food. She's nursing 2, 4-week old babies now, taking care of the kittens just fine. They all did have URI's when they got here, done with the meds last week. She did just get a booster shot last Thursday, maybe a reaction that I'm just noticing?

any ideas? If it is an ulcer, what could that be from and how would it be treated?

If it's a pimple type thing, it may be an ingrown hair, or even a pimple. If it gets any worse or doesn't seem better in a day or two, you might want to get her in to the vet.

I've noticed something similar on my 6 month old, just curious if anybody has suggestions on what it is/what to do for it?

If this does not go away in a reasonably short time, please see a vet.

That being said, I've had that happen to me twice with one particular cat of mine.

The first time, it was actually a reaction to her plastic food and water bowls.  Some cats are allergic to plastic.  Once I changed to metal, glass or porcelain bowls, it went away.

She got it again a few years later.   I had just moved to a new apartment, where there was new carpeting.  It seems there is something in new rugs, carpeting and/or the padding that many cats are allergic to, and that was just a waiting game until whatever that chemical was sort of worked its way out and dissipated, and the rash went away after a few weeks.

But if neither of those are the situation, then watch, and if it doesn't go away or gets bigger, see a vet.
