My cat eats too fast, throws up, and is always hungry. What's wrong?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 8 years and 3 months old | 8 lbs

Ryan has difficulties controlling his appetite. He is deaf. He lives here at the foster/sanctuary. He will eat and eat like he's starving. Doesn't even chew, then throws up. We've tried various diets per the vet. He's now on H/E by Royal Canin. I give him a tbsp Of the wet, then 3/8 of a cup of dry, split up 2x/day. I think its anxiety. I just wish I could slow him down when he eats.

Thank you for submitting your question regarding Ryan. Vomiting is not normal in a cat and a common misconception is that it is due to eating too quickly. While this can be the case, the vomiting is more likely the result of an underlying disease. An increased appetite can be due to diabetes or hyperthyroidism. If possible, it would be best to have him screened for these diseases. Another common cause of vomiting in cats is inflammatory bowel disease. He is eating a high quality diet, but it may be triggering inflammation in his intestines. You could transition to a prescription hydrolyzed diet and feed this exclusively. It may result in control of his vomiting. I hope this information helps!
