The glass lizard, from the southeastern tier of states, requires caging that provides both terrestrial and arboreal niches. Several of these legless lizards can live in the same cage with no conflict. These lizards are active and move quickly. They are also grassland dwellers that dehydrate quickly, so keep a slightly damp (not wet) cage. Keep the sand in one corner of the cage damp. Provide dampness on the lower levels of sand by pouring water through a vertical pipe or tube, which is pushed through to the bottom of the cage.
