Without a proper hide and sleeping area, reptiles can easily develop stress that may affect their well-being and appetite. The Exo Terra Wet Rock offers your reptiles, amphibians or invertebrates a secure place to hide and sleep, while the moist microclimate will support thermo-regulation, hydration, and aid the natural shedding process of reptiles. The unique hygroscopic properties of the ceramic material regulate the cave’s humidity and temperature in a natural way by absorbing and slowly releasing moisture from the water reservoir. Adequate air humidity levels create a healthy environment and help prevent respiratory infections. The natural look of this eco-friendly ceramic cave can be easily integrated into any type of terrarium, and by simply adding moistened Exo Terra Forest Moss or Sphagnum Moss, the cave provides an ideal egg-laying site for various species of reptiles, amphibians and invertebrates. The Wet Rock’s water reservoir should be filled with water at all times to assure that the microclimate retains optimal temperature and humidity levels for your animals (and their eggs). Available in 3 sizes!
