Renal Failure (Cats)

Your cat has been diagnosed with renal (kidney) failure. It is one of the most common diseases of geriatric cats and occurs as part of the aging process. Signs of kidney disease are increased drinking, increased urinating, weight loss and general loss of body condition. These signs come on very slowly and frequently go unnoticed until considerable decline in the cat’s condition has occurred. These signs also mimic those of diabetes and hyperthyroidism.

Diagnosis of kidney failure is based on physical exam and the results of blood and urine tests. The degree of elevation in kidney values can have prognostic value, but all aspects of the cat’s health need to be considered when deciding the best course of action.

Treatment for kidney failure is non-specific depends on the severity of disease and disease state. Generally, subcutaneous or IV fluid therapy, and dietary change is warranted, as well as management of other concurrent diseases (dental disease, bladder infection…). Some cats respond well to treatment and live many more months to years while others decline despite intervention.

Home care of a cat with declining kidney function entails feeding a highly digestible, low protein diet (creates less waste for the kidneys to process), potassium supplements (diseased kidneys let too much potassium go), increased water consumption (easier said than done), and as little stress as possible. Some cats benefit from daily antacid medication to prevent phosphates from building up in the blood.

Renal failure is a serious disease and is not always successfully treated. Please feel free to discuss all the options with us when deciding the best plan for you and your cat.
