I give this food one star because many of Iams foods have By-Products which have NO nutritional Value for animals. A by-product is not the meat it is the beak, feet, undevolped eggs of an animal. There is also too much grain in many of thier foods which are basically just fillers, your animal cannot digest that much grain, and you the consumer will be feeding your animal much more grain then they need to eat. Which down the line can cause digestion issuse's, a hard stool (the stool should be the consistancy of a Marshmello) Pica (when your animal eats and swallows rocks, sticks, sting, shoes, and more non-eadible items) a shorter life, and more.
