Pet's info: Cat | Mixed Breed | Male | neutered | 15 years and 9 months old | 21 lbs
My 15 year old 21 pound yellow tabby male cat has developed a golf ball size lump on the middle left side of his back. There are no puncture holes and it doesn't seem to bother him. He is eating and acting normal. His litter box habit has neither increased or decreased. Any suggestions?
