Pet's info: Cat | Mixed Breed | Male | unneutered | 8 lbs
My cat is around 1 years old, and he has a hard lump about the size of a quarter on his abdomen near his hind legs, and another lump about the size of a nickel on his ribs on his left side. I was just wondering what it could possibly be, and if it could be anything potentially dangerous. You wouldn't be able to tell they were there unless you were petting him, so I am unable to attach any photos.
