Provides a naturalistic shelter for snakes, lizards, amphibians, and invertebrates while helping to prevent stress, bad sheds and egg binding.Create a humid "micro-climate" inside the cave necessary for shedding and proper respiratory functions of reptiles and amphibians.Provides a nesting site, allowing you to enjoy breeding several small species of lizards and snakes. Zoo Med’s New ReptiShelter 3 in 1 Cave is a unique, natural looking, and multifunction reptile den that also functions as a shedding and egg-laying chamber. Many reptiles and amphibians suffer from lack of humidity in captivity, which can lead to shedding and respiratory disorders. The ReptiShelter 3-in-1 Cave corrects this problem by creating a humid microclimate within the terrarium, similar to what they would find in burrows, or under rocks and logs in nature. By adding the appropriate substrate to the 3-in-1 Cave tray, you can provide the ideal environment for shedding and egg-laying. The ReptiShelter 3 in 1 Cave is available in 3 sizes to accommodate most pet reptiles and splits in half for easy access. Small 6" (15cm) For Geckos, Anoles, Small Skinks and snakes Medium 8" (20cm) For medium size Lizards and Snakes Large 12" (30cm) For Ball (Royal) Pythons, Corn Snakes, King Snakes etc
