Feline chronic renal failure is characterized by progressive and irreversible damage to the kidneys. The kidneys are responsible for various jobs such as removing waste products, producing hormones, and controlling blood pressure. They can function normally while operating at just 30% of their capacity, so your cat won’t show symptoms of feline chronic renal failure until the condition has advanced.

Causes

There are various things that can cause feline chronic renal failure. As your cat ages, his kidneys will eventually wear out and lead to the condition. Your cat may also suffer from feline chronic renal failure if he ingests antifreeze, some antibiotics, and certain anti-inflammatory drugs. Various infections can also reduce kidney function.

Symptoms

As mentioned earlier, your cat won’t show symptoms of feline chronic renal failure until about 70% of kidney function is gone. Two of the most common signs include increased thirst which in turn leads to increased urination. Cats with feline chronic renal failure will also experience constipation, vomiting, weight loss, and general weakness. Your cat will also likely lose his appetite.

Diagnosis

The veterinarian will have to perform a few tests to diagnose feline chronic renal failure accurately. Tests are perform on urine and blood samples to measure the level of kidney function. These tests will also show whether or not an infection is causing your cat to show some of the symptoms of feline chronic renal failure.

Treatment

Unfortunately, feline chronic renal failure is not a reversible condition. Some cats can live a few months or years with the condition, while others won’t respond to treatment at all. A kidney biopsy can help determine how long your cat has left to live.

Treatment of feline chronic renal failure isn’t designed to cure the disease, but to help your cat live comfortably. This includes a special diet to decrease the intake of salt and protein. Your cat may also need to take medication to control high blood pressure. Since the kidneys won’t produce enough hormones to maintain adequate levels of red blood cells, medications for anemia will usually be prescribed.
