Acute kidney (renal) failure is a life-threatening illness. Cats of any age, breed, or sex can be affected. Acute kidney failure usually develops within a matter of days and symptoms become very serious very quickly.

Acute kidney failure is often referred to as Acute Kidney Injury (AKI) by vets. It happens when the kidneys suffer damage and stop working. This leads to a build-up of fluid and toxic waste inside the body. Acute kidney failure can sometimes be reversed with rapid and intensive vet care. But it’s a life-threatening illness and around 50% of cats who develop acute kidney failure won’t survive. Cats who do recover may develop long-term health problems, especially chronic kidney disease (CKD). The sooner acute kidney failure is recognised and treated, the better the chances of long-term recovery.
