Another common form of live food, most commonly used to feed snakes, is small rodents. The most commonly known small rodent used for live food is likely the mouse; many pet stores which carry snakes or cater to snake owners also carry "feeder mice" for this reason (see Fancy mouse).
They can be purchased at most pet stores and bait shops. They are also available via mail order and via internet suppliers (by the thousand). Mealworms are typically sold in a container with bran or oatmeal for food. When rearing mealworms, commercial growers incorporate a juvenile hormone into the feeding process to keep the mealworm in the larval stage and achieve an abnormal length of 2 cm or greater.
