Single source protein which is fine but nothing after it. Its followed by brewers rice, corn gluten man, oat meal, barley. All grains and two big time low quality fillers and allergyns in the brewers rice and corn gluten. So bacisally not at all impressed with the food. Would feed proplan over this. I for grains like to see the use of brown rice, potato, or barley. I think a lot of marketing is in this product. Yes there are no animal bi-products, but these is not much else to brag about besides the chix. With so many grains, you will be picking up more poop and may have to watch the food intake to avoid obesity.Chicken, brewers rice, corn gluten meal, oat meal, pearled barley, fat naturally preserved with mixed-tocopherols (form of Vitamin E), dried egg product, soy flour, calcium phosphate, natural flavor, calcium carbonate, potassium chloride, salt, vitamins [Vitamin E supplement, niacin, Vitamin A supplement, calcium pantothenate, thiamine mononitrate, riboflavin supplement, Vitamin B-12 supplement, pyridoxine hydrochloride, folic acid, Vitamin D-3 supplement, biotin, menadione sodium bisulfite complex (source of Vitamin K activity)], choline chloride, minerals [zinc sulfate, ferrous sulfate, manganese sulfate, copper sulfate, calcium iodate, sodium selenite],L-ascorbyl-2-polyphosphate [source of Vitamin C].
