Caiman lizards are kept in private collections, but they are not yet kept in large numbers due to their tendency to only accept snails and their high price. Additionally, caiman lizards are arboreal, aquatic and burrowing, so suitable enclosures are usually only made by zoos. Caiman lizards born in captivity have been known to take a variety of food items, including snails, fish, cat food and crustaceans. Their temperament is comparable to that of a tegu.
