Having had cats most of my life, I have made an observation, regarding cats that are "pukers", I hope this does not offend anyone, but I know their are cats that throw up several times a week (I have two now) & cats that very rarely throw up. I have noticed that cats with the thin, lanky body type seem to be the ones that do this most often, whereas the thick, chunky ones rarely throw up. I have had my two to the vets & they always say its an intolerance of an ingredient to their food, this is not the case, their is no food I have not tried, including California Natural with 3 ingredients. I think their is something regarding this body type of cat that causes the problem. Any thoughts on this? Or suggestions? I dearly love my cats, but their are times when its very frustrating to clean up after them 2 or 3 times a day.
