I hate vegetarian diets for dogs and cats. The nutrients in the food just aren't as usable, and I just don't find it to be healthy. You'll find that most of the problems in animals that result from food, are because of the grains in the food. Vegetarian foods are filled with grains, not to mention a large amount of common allergens and causes of digestive problems...I read some of the ingredients on a Vegetarian kibble bag the other day...Lots of corn and soy to up the protein amount. The protein in soy and corn aren't very usable...Meaning the animal isn't getting enough protein. I don't think vegetarian diets are healthy at all.
