Although cats of any age can develop acute renal failure, cats that are more than 7 years old are more prone to chronic kidney disease, WebMD explains. There are many possible causes, from kidney blockages to thyroid problems. A cat that urinates frequently, has bloody urine, drinks excessive amounts of water, has diarrhea or constipation and shows signs of weakness is likely to have some sort of kidney problem or kidney failure. Once consulted, a veterinarian does urine tests, blood tests and ultrasounds on the cat to determine the cause of the symptoms. If the kidney is at fault, the cat is given mediation and fed a diet rich in omega-3 fatty acids and vitamin D.

Hyperthyroidism and thyroid problems are other issues associated with an aging cat with symptoms similar to kidney failure, such as increased thirst and urination, diarrhea and vomiting, according to WebMD. Furthermore, the cat experiences increased shedding, panting and hyperactivity. This can be treated with the removal of the thyroid, antithyroid medications or radioactive iodine therapy.
