Natural, hand-crafted center for reptile activity. The three activities reptiles enjoy most...basking in the warmth, climbing and relaxing in a cool burrow...can all be accomplished in the comfort of a Stump Den. Reptile owners like it too, thanks to a realistic faux bark finish that cleans easily with soapy water. Since the stump's non-porous exterior surfaces won't retain water or promote bacteria, terrariums stay healthier and smell fresher longer. Safe for both aquatic and terrestrial environments. For large or mature reptiles, choose the roomier medium size.
