Note: Most of the cat food sold in stores is dry, also known as kibble in the United States, or in the form of wet cans. Some manufacturers sell frozen raw feed and premix products to meet the needs of cat owners who make their own cat food.
Dry food (8-10% moisture) is usually squeezed and cooked under high heat and pressure. Fat will be sprayed on food to increase palatability, and other trace components, such as heat sensitive vitamins, will be damaged during extrusion, which may increase.
Canned or wet grain (humidity 75-78%) is usually 3 ounces (85 grams), 5.5 ounces (156 grams), and 13 ounces (369 grams). It will also be sold in the form of aluminum foil bags.
Vegetarian and vegan cat food sales. Vegetarian cat food must be fortified with nutrients, because cats are born carnivores and cannot synthesize these nutrients from plant foods, such as taurine and arachidonic acid. Some vegetarian cat food brands are labeled with their manufacturers following AAFCO cat food nutrition standards.
