Is polycystic kidney disease a death sentence for a cat?
Polycystic kidney disease is not a death sentence for a cat. Some positive cats can have long life. It depands on how bad the kidney failure is and what % of the kidney is still functioning. A friend of mine had a persian male who was positive by DNA but the kidneys were normal and showed no symptoms of the disease. Unfortunately when it is bad and the kidneys are not functioning any more there is nothing much you can do to help your cat.
