The commercial pet food industry has a secret to hide — and Ann Martin wants to make sure you know it in her book titled "Food Pets Die For: Shocking Facts About Pet Food". Her research reveals some startling facts: that the pet food industry conducts animal testing in order to improve their product, and includes euthanized cats and dogs in the mix to heighten protein content. In this revised and updated edition, Martin continues to explore the shocking processes by which commercial pet foods are produced (see: Google Books).
