Like the others have said, they may climb some, to reach the heat of the lamp. But they love to get into the hides. I would suggest one thing though. Use newspaper to line the terrarium then put shredded newspaper on top of that. Don't use regular paper or stuff from the mail. That paper is too stiff, I guess you would say. I used the coconut stuff, that wasn't good for my beaudreaux. Good Luck!
