The last couple of times I have fed Smilla one of my cats has immediately thrown it all up. As it was so soon after eating I assumed it was due to scoffing it too fast. This evening I tried him on a small portion and again it all came up, but after about an hour this time, so not immediate regurgitation plus there wasnt a great deal in the bowl. My other kitten has not thrown it up. The sicky kitten is fine on bozita, animonda, and grau (had bozita this morning) and only throws up Smilla. Is there anything in this food which could be causing him to only throw that up?
