Poor Tiger

Remember Tiger? Connor's cat who we got from a shelter (obviously found dumped on the side of a road somewhere) who subsequently got run over shortly after we got him (don't ask). We spent a small fortune fixing this cat's leg and doctoring his wounds. He recovered and then shortly after began sitting in the litter box day and night. Back to the vet again and a few short bills later we find out the dam thing has some kidney failure. Thank god there's no kitty dialysis. But we spent another small fortune on cat food that was special to his needs for the kidney failure....needless to say it didn't help. Well, now he's back to sitting in the box all day and night. When I went to change the box yesterday he jumped in it and we noticed he has blood in his urine. Bad sign. Back to the vet again today. I honestly don't like this cat but by god we've already spent a small fortune on this thing. He will live until he's 20yrs old if I've got anything to do with it. Wish us luck.
