I live in an apt and my car is parked far away I don't have a cord right now. I left water bottles & a mouse in the car but everything's getting cold so fast she probably won't be able to sense the heat. I need something that stays hot. I might have to go buy a heat pad. It's going to be hot tomorrow again I might leave the mouse in my car then because the smell would be more prominent then, my cars going to stink lol but I need to find this snake :/
