Inspired by the diet of the lynx, a tireless hunter and wild relative of our domesticated feline friends, protein-rich BLUE Wilderness contains a higher concentration of the delicious chicken you know she'll love, plus other natural quality ingredients. BLUE LifeSource Bits are a precise blend of antioxidants, vitamins and minerals selected by holistic veterinarians and animal nutritionists to help support your cat's health and well-being. And LifeSource Bits are cold-formed to help retain the potency of their ingredients. This means that we minimize the amount of heat that LifeSource Bits are exposed to during the manufacturing process. It's the same concept as when you cook vegetables at high heat the longer you do, the more heat-sensitive nutrients are lost. BLUE Wilderness Indoor Hairball & Weight Control Chicken Recipe is formulated to meet the nutritional levels established by the AAFCO Cat Food Nutrient Profiles for maintenance.
