proper hiding area is an often-underestimated feature of a terrarium. Without a safe spot to sleep or hide in, reptiles and amphibians easily develop stress that can effect their activity and appetite. Hide-outs also provide reptiles with shelter or a "cool spot" in the terrarium. The Exo Terra Reptile Cave provides your reptile with a safe hiding place and its natural look integrates in any type of terrarium. Easy to clean and built for stability.
