Does anyone know if these are safe? http://www.zoomed.com/html/heat_cable.php Are they a burn hazard for a reptile? Are they a fire hazard? Are they as good as a heat lamp or ceramic heat emitter? My husband gives me a hard time about lamp bulbs burning out as often as they do, so I'm thinking of changing to something else. I can't use a heat mat because I don't use a thick substrate (I use newspaper and/or paper towels), and I'm afraid to use human heating pads because of possible fire hazard. I've been thinking about getting ceramic heat emitters, but I saw this online and wondered about it...I've also considered radiant heat panels...are they safe for reptiles and not a fire hazard?...what do you all recommend the most?
