Commercial pet food refers to pre-packaged food products specifically formulated for pets, such as dogs and cats. These foods are designed to meet the nutritional needs of animals and are available in various forms, including dry kibble, wet canned food, and semi-moist options. Manufacturers of commercial pet food often follow guidelines set by organizations like the Association of American Feed Control Officials (AAFCO) to ensure the products provide balanced nutrition. Ingredients can vary widely, ranging from meat and grains to vegetables and added vitamins, catering to different dietary requirements and preferences of pets.
