African pygmy hedgehogs are 5 to 8 inches long and can live for up to five years. They eat insects, such as mealworms and crickets. Specially formulated commercial hedgehog diets made out of mashed-up insects are available for sale. Hedgehogs are often kept in cages, but they require large amounts of exercise to remain healthy and should be supplied with an exercise wheel.
