I have a home made cage. Its 6x3x2 plywood with plexiglass and wood door. I dont even remember anymore what the heat source was when I got it. I know eventually it burned the linoleum that was on the bottom. Since then I bought a small heat pad type thing and that eventually burned out. I moved what was in it out and ripped up all the old linoleum and caulk. I have new linoleum to put down but am unsure what to do about the heat. It needs to be inside the cage (cord can run out between door and side of cage)but I am wondering about something again "burning" the linoleum. Is there something I can put under it that will be safe? There is a ceramic fixture in the ceiling of the cage so I am able to put a minor heat source there. Can someone suggest something that would be safe. I've read a lot of these threads but so much is initials I cant be sure what most of it is.
Thanks.
