I was petting Willie yesterday and as I went down his side I felt a lump on his left side, a few inches in front of his hip. It's a decent size, maybe a 1/2 inch across. He just turned 6 a few days ago. I'm feeling sick to my stomach about it. I don't even know if we have the money to go to the vet at the moment and have it tested (but we will, eventually), never mind the treatment needed for something like cancer. Please send vibes and Prayers for Willie, I need him to be okay. What sort of cancer would present itself on his side like that? Anyone ever have a cat lump turn out to be nothing? I know dogs tend to get fatty tumors, though usually when older, but I feel like cats don't get them so much.
