Hi there and thanks for posting! If you cat has a lump or mass that has appeared to have ruptured, I would visit your veterinarian right away. The mass may need to be removed or treated with antibiotics. Your veterinarian may also take a sample of the mass to determine what it is and if it needs to be removed. I hope this helps and thanks for using Petco Pet Education Center, formerly Petcoach!
