My older "family" cat that lives with my Dad was just diagnosed. We believe him to be about 16. The Dr says that other than the beginnings of the kidney failure he's in great health for his age. We've been told that a special diet made to help his kidneys will make him feel better. This is the very early stages, but we weren't given a time frame as to whether or not we have months or years left. Just looking for other experiences to help us through. Thanks!
