Authentic look, designed for easy care. Reptiles and pet owners both benefit from the presence of Shale and Lava Rocks in a terrarium habitat. Pets get a natural opportunity to hide in cleverly designed rock niches, satisfying a healthy desire for coolness, privacy and protection. Owners enjoy easier cleanup, thanks to a non-porous synthetic finish that resists bacterial growth, cleans quickly with mild soap and water and is safe for both aquatic and terrestrial environments. Best of all, visitors won't be able to tell these naturalistic decorations from the real thing.
