Hi, I posted recently on what I thought was a gum problem in my cat Harley. It is actually on his bottom lip. (I wish I could take a picture of it and post it here) There is a sore on his bottom lip that looks like a little bump. He's had this for a few days now. He does not have sores anywhere else. My biggest worry is cancer of course, but he's less than 2 yrs old. I've also read about granulomas and allergies, this is probably more likely. Has anyone had cats with these conditions affecting the bottom lip? He eats out of paper bowls (I hate dish washing with 3 cats) I don't know what he can be allergic to?! He's a feral, so the vet would probably have to knock him out to examine him.
