I think my cat is a vomiter... He was sick two months ago and vomiting was the big sign, mounds and mounds of food one night and heaving when he was empty... but once a week or so for about a month there's a clump of food in my living room or dining room. This has only started happening since I switched him to a wet/dry diet (Nutro dry and Friskies cans wet) two months ago after he was well again. I measure the dry food, and he only gets about a third of a can a day. Is he just not liking the Nutro, because with the Friskies dry he was not doing this, or is the mix of the ingredients in the foods that's doing this? I should add that he was at the vet again almost two weeks ago to get neutered and his blood work was normal.. so he isn't sick. Any advice?
