Fair enough, I may stand corrected. The food I give my dogs and cats include organ meats, tripe, chicken, muscle meats of all kinds and fats. I believe they get all the nutrition they require from the foods they eat. I make my own foods adding in sprouted alfalfa, kelp and sea weed all mushed up in a blender and mixed in to the foods. I'm a firm believer in home made is best. I love all my animals and give them the best I can.
