I'm not talented or creative like many of you are with building wood shelters and night boxes. Where I live, the coldest it will get this winter is maybe 45 degrees, and that's not often either. I wanted to create some type of shelter where my Russian Tortoise can go if its raining hard or if it gets cold. I saw these items on Amazon and thought I'd give them a try. The heating pad is made of ABS plastic and the temperature is adjustable from 80-100 degrees. I though of putting it in the box with a layer of topsoil as a safe place for RT. One concern I have though is if it will attract snakes as that is my one phobia. Has anyone used a setup similar to this? Will the heating pad be sufficient?
