Dog ate chocolate?

Brown spot on lip of dog.

Species: Cat
Breed: Long hair, no other
Age: 2-5 years
Greetings,

I have noticed that my cat has problem with her mouth.

On the lower left gum (I actually think it's the lip), there's a brown patch, nearly a centimeter long.

Where the healthy skin meets the brown skin, it digs a little into the lip. I haven't notice my cat having any problem eating, I still hear biting regularly and I'm not certain if there's an odour or not. I think it smells normal.

This patch is clearly out of place and it makes me think it's some kind of unhealthy growth but I have not had any success finding similar examples on the net.

I appreciate any insight you can give me, thank you!

It's always tough to answer skin questions over the internet but I can give you a few of my thoughts!

I am wondering if Whisper has something called an eosinophilic ulcer. We don't really know what causes these although we suspect it may be connected to allergy. Sometimes they will go away on their own, but often they will need one or more steroid injections given by the vet.

Some cats can get pigment changes that are normal but you shouldn't be seeing an erosion.

A wound of some sort is possible to.

It does sound like a vet visit is a good idea.

Dr. Marie.
