I discovered that those exo terra reptile dens which half attach to the outside of the den and the other part inside work both as a warm den and a perfect shedding micro climate. I recently got done testing them with 2 geckos (one adult and one baby) for a period of 3 months and typically they all complete their sheds from beginning to end within 12 hours. One of the great benefits is that because the inside of the reptile dens have a rough surface it makes it easy for them to rub up against them, something that is unable to occur inside a tubberware container. Anyway, I have just placed an order for 3 more of them, sure does save me effort having to monitor sheds. http://www.exo-terra.com/en/products/reptile_den.php
