Dog and cat owners encounter a dizzying array of choices and confusing labels when shopping for pet foods in supermarkets. They will welcome the information Nestle (nutrition, New York Univ.; Pet Food Politics) and Nesheim (nutrition, emeritus, Cornell Univ.) obtained from their research and firsthand experience. Readers learn what pets are supposed to eat (dogs are omnivores; cats are carnivores) and the scientific standards and government regulations that led to the development of commercial pet food. Owners are guided through the many food choices, including dry, canned, wet, and semimoist foods; products called "premium," "all natural," "prescription diet," and "hairball control"; and more unconventional diets, like raw, vegetarian, and home cooked. After discussing various foods and nutrients, they conclude with specific and sensible recommendations for pet owners, the industry, and the government. VERDICT Filled with useful information, this well-written guide is the pet nutrition counterpart to Nestle's human nutrition guide, What To Eat. Recommended for all pet owners.—Eva Lautemann, Georgia Perimeter Coll. Lib., Clarkston
