Kidney (renal) disease in cats happens when their kidneys stop working properly. Kidney disease may be chronic (comes on gradually) or acute (sudden).

Chronic kidney disease (CKD) is one of the most common illnesses affecting cats. Cats of any age, sex or breed may develop chronic kidney disease, but it’s most common in older cats. Around 30% of all cats over 10 years old (of any breed) have chronic kidney disease, rising to 50% of cats over 15 years old. Younger cats who get chronic kidney disease are more likely to belong to certain breeds, including Maine Coon, Ragdoll and Siamese.

Kidneys carry out essential functions in the body. As cats get older, their kidneys become less efficient. The reason why this happens isn’t known. There are triggers which can make it happen earlier or progress quicker. These include toxins, infections and other illnesses. There’s no cure for Chronic Kidney Disease. Eventually, the kidneys will fail completely. But the rate of deterioration varies between cats. Symptoms of CKD can often be stabilised for prolonged periods. Early diagnosis and treatment help achieve the best outcome for the longest time.
