I can't add anymor ethna what has already been said. Cats can life a good few years with chronic renal failure and can be comfortable if they receive the correct treatment. Some cats tolerate fluids well but a few don't - you have to be patient and appear confident and explain everything to your cat. I too would strongly suggest joining the feline CRF yahoo group as they will have much experience of renal failure in cats. Even though you trust your vet (and it is good to have a have you trust and who has a connection with your animals) it doesn't mean he knows everything or even what is best for your cat because as we all know too well that isn't always the case and no-one knows your cat better than you.
