I had a cat that vomited from dry food, I switched to grain free canned and it stopped, it's worth a try!My 11 neutered male vomits every night, have been to vet numerous times, tried pills which he fought so much, now on vet G/I special dry food and hairball laxative. Trying grain-free foods, so far no difference, Any Suggestions, Don't live near big pet food stores, just Petvalu........
