I took my 11 year old cat to the vet a little bit ago because a lump had began forming behind my cat's ear. His balance had been off and he became only able to eat a specific type of canned food. They said it was some type of Abscess and they didn't know if it was because of an ear infection or because of his teeth because they've been in bad condition and the dental procedure is very expensive so I can't afford it at the moment. They gave me something to put in his ears in hopes that that would be the issue and the abscess did not change. Now it has gotten much much larger and so I thought it was his teeth since his ear treatment didn't work but now I'm finding a lot of brown gunk filling his ear and when I started to clean out what I could and found little bits of fresh blood. I'm just curious if anyone has some insight that might be helpful
