i have my ball in my room in the basement, i have a vent in my room that blows in hot air and as long as my door is closed it stays 65-70. If theres a way to do this and alomst seal the room it wil stay nice and toasty. I would stay away from space heaters. Also try pre scenting http://www.ball-pythons.net/modules....warticle&id=60
