My cat has pancreatitis. Are cranberries causing his vomiting?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 15 years and 10 months old | 15 lbs

My cat was diagnosed with pancreatitis. We completed allergy testing per our vet's suggestion. He is allergic to pork, tomatoes, green peas, turkey, and corn. We have switched out all of his food. It took me the longest time to find a dry food he could eat (he eats dry and canned food). I finally found one that does not have his allergens and he likes it. But he is throwing up a lot again. Are cranberries bad for pancreatitis? They were not in the tested foods.

Pancreatitis in cats is relatively poorly understood, like your vet suggests allergy is thought to play a part in starting the inflammation process in neighbouring organs. IfMylo is allergic to peas etc then it is quite possible he is allergic to cranberries also. Sometimes berries upset the stomach which could lead to inflammation and aggravate the pancreas. You could try cutting the cranberries out and see if that helps. Apart from that all you can really do is try and avoid the allergic foods, and there is a school of thought that thinks non processed food is beneficial.
