Ok my radiant heat panels for Boyd the boa constrictor's large wooden enclosure just arrived and I have 2 problems I need advice on: 1.) I have a smaller radiant heat panel around here somewhere so I know they get quiet hot plus it says right on the panels: DO NOT COVER! Boyd's substrate is newspaper since I feed him in-cage (and no feeding him elsewhere is not an option, he's too big) and sometimes he burrows in the newspaper and kicks it up and I'm afraid he'll get it on the panels and start a fire. What should I do about that? Maybe stick a few large rocks or something in there to hold the newspaper down? 2.) His hide is a giagantic carboard box, which he also tends to move, and I don't want that pushed up against the panels either. Suggestions?
