The urinalysis will look for proteins in the urine that have leaked through the damaged kidneys and will measure the specific gravity of the urine. Because kidney failure causes the kidneys to no longer filter urine waste, a cat suffering from kidney failure will have urine with a gravity very similar to distilled water. The biochemical profile will look for waste products in the blood that the kidneys were supposed to filter; a high number of these products is indicative of renal failure. Treatment of Kidney Failure in Cats Treatment of Acute Kidney Failure Cats that suffer from acute kidney failure due to trauma or poisoning often recover once the primary problem that caused the kidney failure is resolved. This may include surgery, medications, fluid therapy, or blood transplants. If the kidneys do not respond after treating the primary problem, additional courses of treatment will be needed to address the kidney failure. Dialysis Hemodialysis is a procedure in which a machine acts like kidneys, filtering the blood from waste and toxins that build up in the bloodstream. Hemodialysis can be used to treat cats with chronic kidney disease or to remove a poison from a cat with acute kidney disease. Unfortunately, dialysis is only available in some veterinary hospitals in the United States and can be extremely challenging
