Says Planet Green: “Most conventional pet-food brands you find at the supermarket consist of reconstituted animal by-products, otherwise known as low-grade wastes from the beef and poultry industries – you know, inedibles you wouldn’t touch with a 10-foot fork. . . . Natural and organic pet foods use meats that are raised in sustainable, humane ways without added drugs or hormones, minimally processed, and preserved with natural substances, such as vitamins C and E. Certified-organic pet foods must meet strict USDA standards that spell out how ingredients are produced and processed.”
