So winter is coming around and it's gets down past freezing at night in the winter. Last winter we had a heating pad that was for reptiles, (you know the kind you stick to the underside of the cage?) and a heat lamp always going, since he had a plexiglas bottom. Now he doesn't have a plexiglas bottom for his cage but I think he needs extra heat soon. So should I add plexiglas to the bottom of his current home? I'm worried about a fire... Or I was considering getting him a zoo med rock heater. Does anyone have a good experience with this type of heating?
