I have a 10 year old male cat named . He eats everything in

Customer Question

Hi, I have a 10 year old male cat named Jack. He eats everything in sight, and then shortly after all food sources have been exhausted (his bowl, his brothers bowl and even my Chihuahuas bowl), he sometimes throws up and is hungry again. Also, even though we keep a clean litter box, he sprays in several areas of the house. His brother is from the same litter, but with none of the same behaviors. What does this indicate?

Such polyphagia (increased hunger) is pathognomonic (specifically indicative) of both hyperthyroidism and diabetes mellitus. His inappropriate urination is consistent with hyperthyroidism but simple marking behavior can't be ruled out. All diabetics should also be polydipsic (increased thirst) and polyuric (increased volume of urine). Only 35% of hyperthyroid cats are polydipsic/polyuric. Jack's vet will want to thoroughly examine Jack including diagnostics in the form of blood and urine tests. You should know within 24 hours how Jack can best be helped.

Please respond with further questions or concerns if you wish.
