Exo Terra canned foods are a convenient way to eat insects and snails that are cooked and processed to maintain your nutritional value and aroma for as long as possible. The exoskeleton in the settlement is softened, for easier digestion and destroyed when the collagen protein is returned, which must be made digestible by the drains. Collagen is important for building bone, cartilage, skin and nail structures. Canned settlements have nutritional content as inhabitants, but are better accepted. It is not necessary to add live insects to processed (canned) foods.
