Exo Terra Large Corner Cave PT3197 – Ceramic Reptile Hide

The ET Large Corner Cave PT3197 is a hygroscopic ceramic hide designed to fit snugly into the corner of a vivarium or terrarium, creating a humid microclimate that supports thermoregulation, hydration, and healthy shedding. Suitable for reptiles, amphibians, and invertebrates, it works by drawing moisture from a built-in water reservoir and releasing it gradually into the surrounding air — no electronics, no guesswork.

How the Ceramic Material Works

The cave is made from a hygroscopic ceramic that naturally absorbs and releases moisture, regulating both humidity and temperature within the hide without intervention. This steady, passive humidity management helps reduce the risk of respiratory infections and prevents the sharp fluctuations in moisture and temperature that stress animals and disrupt the shedding cycle.

Space-Saving Corner Design

The corner-fit shape makes use of otherwise wasted space in the enclosure, adding a three-dimensional dwelling area without eating into the central floor plan. The natural finish integrates cleanly into bioactive, naturalistic, and standard terrarium setups alike.

Maintaining the Microclimate

The water reservoir should be kept filled at all times to ensure the microclimate remains consistent. For the large size, the reservoir holds 150ml of water. Adding moistened moss — such as forest moss or sphagnum — transforms the cave into a suitable egg-laying site for a range of reptile, amphibian, and invertebrate species.
