Cat health symptoms of kidney problems can lead to serious health issues for a cat. Chronic kidney failure happens to older cats more than it does to younger cats. Cats develop kidney problems gradually over time and usually do not show any signs until it becomes serious. With proper check ups and blood tests veterinarians can find problems before they become more serious.

Causes of Chronic Kidney Failure

Once a cat has chronic kidney failure, they will need special care and treatment. Kidney failure is irreversible and can lead to other health problems. Kidney failure is caused by many different reasons including trauma, bacterial infections, medications, toxins and cancer along with fungal infections and autoimmune disease. Kidney failure may also be due to hereditary or congenital abnormalities.

Some Cat Health Symptoms of Kidney Failure

One sign the cat has a medical problem is inability to urinate. The chronic kidney failure problem may be caused by kidney stones, urethral obstruction or bladder stones. If this symptom occurs, seek immediate medical attention before the problem becomes fatal to the cat. Kidney failure shows no early signs, but as it progresses, sign start to appear.


Another symptom of kidney failure is increased thirst. Because the cat is drinking more water, the urine does not bring along all the toxins in the kidneys, which remains in the kidneys and results in kidney failure. Other cat health symptoms of kidney failure are poor appetite, depression and lack of energy.

Cat health symptoms of kidney failure are diagnosed by blood tests and urinalysis. The BUN levels of a cat with kidney failure will be higher than a cat in perfect health. The Creatinine levels will also be higher than normal, which leads to the diagnosis of kidney failure in the cat.

Treating Chronic Kidney Failure

Treatment of kidney failure in cats requires kidney transplant or dialysis. By the time kidney failure is diagnosed the cat may already have so much damage to the kidney that any type of treatment would not benefit the cat and a decision to euthanize the cat before any more suffering occurs would have to be discussed.

Because every owner wants their cat to live a healthy and happy life kidney transplants have become more popular in cats and has allowed them to live a good life. If a kidney transplant does not happen, other methods of treatment may help the cat such as dialysis, which in most cases does work as it filters the kidneys and eliminates the toxins. This procedure requires weekly visits to a veterinary clinic for treatments, which requires a few hours of treatment. For more info see

If the cat has kidney failure a low protein diet helps maintain lower BUN levels, which helps with the metabolic system, but not the renal problems. Proper diets and proper fluid intake requires dedication on the owner’s part. If the cat has a kidney transplant, hospitalization and further medications will be required for a successful kidney transplant that functions properly.
