So generally i wouldn't even consider using a heating mat for a reptile, but my tegu i got just this last summer is now brumating and our house gets quite cold at night. I don't want to keep her day bulb on 24/7 so i have been testing out a heating pad underneath and she really seems to enjoy it. Just wanted to get some peoples opinions on it since I have never really dealt with them, wouldn't want to burn her!
