I'm curious as to more details also.

Tubby was diagnosed with chronic kidney failure about 2 years ago now, and he's doing fine. I originally took him in because he was throwing up just about every day. They did a blood test on him and found his levels indicated the kidney failure. The vet told me to give him a 1/4 of a Pepcid (antacid) every day. The vet said the Pepcid wouldn't reverse any damage that has already been done, but it would slow the progression of the disease. When I took him in for his 6 month check-up, the vet was pleased to see that one "level" had stayed the same - meaning it had stabilized - and the other level had actually improved! He had gained weight too since he wasn't throwing up all the time. The vet said the Pepcid increases blood flow to the kidneys - which helps them work, and it also calms the acids in their tummies so they aren't throwing up all the time.

So, I guess what I'm trying to say is, unless is acute, renal failure isn't necessarily a death warrant. I know kidney failure is common in older cats, but just live everything else these days, they are making more and more progress on treating the old age diseases of kitties, just like they are in humans. So please ask your vet about the Pepcid or similar treatment.

The last checkup Tubby had the vet actually said (her words) "He's doing remarkably well for a guy his age." He's 17 now, and I expect him to be around for quite some years yet.

So good luck at the vet tomorrow, and please let us know how things go.
