Hi Heather– thanks for your email. There are many causes for vomiting in cats. It can be anything from plant ingestion, dietary change, dietary indiscretion, foreign body ingestion, metabolic disease such as diabetes mellitus, kidney failure, or inflammatory bowel disease just to name a few.

If the vomiting is persistent, your cat acts lethargic, is loosing weight or not eating, I’d recommend that you take him to your vet for an evaluation.

An article that might be helpful to you is Vomiting in Cats.

Best of luck!
