I have 3 cats and during the night one or more of them vomit. I don't know which one it is and don't know how to figure it out. I have thought about switching their food but one of my cats has urinary problems and we have to feed him purina one urinary tract health food. The cat that has that problem is a male. I also wonder if feeding all my cats this food could be causing the vomit in one of the cats because she is a diabetic. Is there any way to be able to single out one cat for the issue. Could I color the food? I have also thought about switching just one cats food, but I am afraid that my male cat will start eating the other cats food. Does anyone have any suggestions on how to figure out what cat it is?
Thanks
