Burrow-friendly bark for tropical/forest habitats! Reptiles from a variety of habitats...from the tropics to northern forests...will thrive in additive-free Douglas Fir bark. Loose and light enough to encourage natural burrowing behavior, this material promotes the free transfer of heat and moisture essential for the health of cold-blooded pets. Made of 100% natural ingredients harvested in the USA, and readily biodegrade in a backyard compost at the end of its useful life. Ideal for Chameleons, Frogs, Rainforest Geckos, Salamanders & Newts.
