Pet's info: Cat | American Shorthair | Male | neutered | 5 years and 3 months old | 12 lbs
On Monday or Tuesday, I noticed that one of corners of my cat's mouth appeared red and swollen. And, on the inner side there was a small circular white patch. Today I noticed it looks worse. It looks a bit weepy, and he doesn't close that side of his mouth. Sometimes it seems like he has a bit of trouble eating. He also has black specks on the side of his mouth that were never there before. Any insight is greatly appreciated.
