Just put the snake in a Tupperware container or a small plastic sterilite container or anything with a lid. Punch a couple holes in it and just turn the heat on in the car. I've had to actually pile all my gals in their tubs and put them in the car and run it for hours with the heater on when I lost power for like 12 hours and forgot to restock on UniHeat warmers. And guess what...I lost power again this past sunday and was out of UniHeat warmers againAnd my local pet shop that carries them was sold out and Bean Farm who I live close to was closed. Luckily I got some from my hardware store. Anyways, just put them in a container and turn the heater on so its comfortable.
