WHY??? does the woman in the video state the heating pad is not a fire hazard? Recently a heating pad started a fire at a zoo, did a lot of damage and killed animals. I'm assuming there is a reason heating pads are mostly now made with an auto shut off. Believe directions say not to cover the heating pad but in this chick warmth application it's not covered underneath and with hay some heat can escape through the top so it's safe to not over heat. I guess if nothing chews on wires or they are damaged it may be pretty safe. What say you??? It's a fantastic idea and I'd like to do it as well. I'm going to look for "Kingsize Sunbeam Heating Pad" now and hope they make it with a "leave on all time" option.
