You want to monitor your Exotic Pet but don't want to keep disturbing it. Now you can purchase a magnetic reptile den which simple fits to the glass in the vivarium.
This reptile den made by Exo Terra has to parts, one that sits next to the glass inside the vivarium and the other section on the outside. With a "through-the-glass" magnetic rock formation, you can now check your Exotic Pet without disturbing it.
Simply remove the outside part of the cave and you can see what your pet is up to without causing any stress to the animal. The inside of the den is also insulated to keep this cool, just like in nature.
