My wonderful kitty, Benny hasn't been eating and has lost a lot of weight. He's 10 years old and I thought he was just eating less because of his age. The only thing he'll eat is tuna in water. He is fascinated by the water coming out of the faucet and recently that's how he drinks. I took him to the vet last week and they did blood work. He's in renal (kidney) failure. I've been giving him iv fluids daily and the vet told me to feed him Low protein and low phosphorus. Unfornuately he won't eat any of these foods. The vet said "No tuna". I'm so worried so I thought I'd ask if anyone has had the same experience and any suggestions!
