We use a low ash, chicken meal, a high quality protein source that contains muscle meat. By AAFCO definition and law, it cannot contain heads, feet or intestines. Our chicken meal is high quality and does not contain any “4-D” ingredients (dead, dying, diseased or disabled animals) or any other waste products. We do NOT use Chicken by-product meal, which contains various parts of the chicken, including heads, feet, intestines.
