Answered By

A. More information and a complete physical exam would be required to diagnose illness. It would seem your cat has liver and kidney issues which are not uncommon in older cats. Frequently, results like this require more diagnostics such as complete blood work (CBC, chemistry panel, thyroid panel and urinalysis with culture) as well as imaging (either abdominal xray or ultrasound to visualize kidney and liver architecture. See your vet for a recheck or further diagnostics if your cat is exhibiting symptoms such as decreased/increased appetite, increased thirst or urination, lethargy and weight loss/gain.
