Many of the Science Diet formulas contain ehtoxyquin and BHA/BHT, which are carcinogenic preservatives linked to cancer, epliepsy, stillbirth, disease in puppies, etc. Ethoxyquin is a chemical rubber hardener and powerful insecticide that is illegal in most places of the world. They used to spray it on lawns until they discovered it was causing bad adverse health issues in people. Since it kills things, it's very good at killing bacteria, and thus is added to some Science Diet formulas. Science Diet is also owned by Ralston Purina, a company that is big into animal testing.
