Why does my cat throw up right after eating wet or dry food?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 1 year and 5 months old | 24 lbs

Hello! My Maine coon has been having issues with wet food. It wasn’t until a couple of months I noticed that right after he would eat wet food or he would vomit it right after eating, almost instantly. I thought this was because of the wet food I was giving him but I have also tried other brands and he still vomits maybe 1/10 times. Smaller portions at a time seems to not upset his stomach though, but vomiting isn’t limited to wet food, he sometimes vomits normal cat food for sensitive cats too.

Thanks for visiting Petco Pet Education Center, formerly Petcoach. Vomiting in cats can be caused by several things, but vomiting right after eating does bring to mind a couple of possibilities. But you first have to differentiate whethere whether Coix is vomting (obvious retching and forceful expulsion) or regurgitating (undigested food just seems to come out without much effort). Vomiting can be caused by inflammatory bowel disease, megaesophagus (typically causes regurgitation), a parasitic infection (not as common), or even an underlying congenital disorder. Most of these conditions are treatable. You should first start with some diagnostic testing to gather more information on your specific pets condition. Then we will know what needs to be done for Coix to help control his vomiting episodes a bit better. In general, you can continue to feed smaller portions and go with an easily digestible diet such as limited ingredient diets (i.e. Iams, Purina, Evo). This is something you can easily start while awaiting a proper vet visit and diagnostic work-up for Coix. I hope this helps get you started and best wishes on finding the exact underyling cause for Coix's vomiting episodes. Take care.
