The new Zilla Rock Lairs are naturalistic decor designed to be used not only as a dark den for your reptile but also as a humid hideaway. Humidity is important in helping reptiles shed their skin and keeping eggs from drying out. A large entrance provides easy access for the animal and also allows for fresh air exchange. The design of the entrance ramp and walls reduces light, mimicking a reptiles natural burrow. The mossy looking surface looks great and doubles as a rough surface to help with sloughing old skin. The Zilla Rock Lairs are available in 3 sizes to suit reptiles from tiny geckos to large snakes and everything in between.
