People, how cold does it get before it's too cold? My daughter priority overnighted our leopard gecko with a heat pack that will last till 8:30 am tomorrow... he was supposed to be delivered today but instead the facility shut down at 1 pm with him inside it... they say they will deliver him by 4:30 pm tomorrow but I am afraid if his heat pack runs out at 8:30 a.m., he will die if they keep him in the truck... there is no one in the facility right now... I am thinking I could awaken in the morning and call them at 6 am. and tell them to put him in a warm room?? if it's 12 F will he die? How cold is too cold?
