Natural Hiding Place Natural look, integrates in any type of terrarium Provides a secure hiding place Prevents stress Very stable, not easily tipped over by larger reptiles The Exo Terra Tortoise Cave was especially designed to provide tortoises with an enlarged hiding space. A proper hiding area is an often-underestimated feature of a natural terrarium. Without a safe spot to hide and sleep tortoises will easily develop stress that will affect their activity and appetite. With its realistic pebble design and large hiding volume the Exo Terra Tortoise Cave mimics the natural hiding places of tortoises. The Exo Terra Tortoise Cave provides shelter as well as offering a cooler and more humid microclimate in your terrarium.
