So yours might just be one of those who need extra nutrients, or perhaps some ingredients in the diet
are making him sick. Purina
has a lot of by-products and grains, corn, rice, and stuff kitties don't really benefit from, as obligate carnivores that they are. So I'd go with either Wellness, Nature' Variety, EVO, Wysong’s Au Jus Canned Meat, Merrick, Country Pet, Avoderm Select Cuts, or even Wysong’s Archetyp. These are all high quality, grain free diets. And yes, grain can cause loose stools.
