I have a 3 yr old male cat, who had an open wound on its belly. I went to the vet and she cleaned it out and I was given antibiotics for him, well he started getting few more open wounds and the hair was missing around the open wound and hard places on his belly, surgery was performed, all of the mass was removed, the vet told me he thought it was tumors and it would clear up or not clear up. I did not pay for a biopsy. All was fine for 6 months now the mass is back, hard again, and open sores again, and the sores are getting larger and more open. I am putting my cat down tomorrow. I love my kitty, but I dont want him to live like this. I have asked every cat owner I know if their cat has ever had open sores appear on their belly, and no one has. I dont ever want to go thru this again or any cat I get. I wonder what happened or if I did anything to cause it. I have seen many cats who live outside, never go to the vet and they are fine. I went to the vet plenty, my cat slept in my bed, was babied, but now all these open sores......
