Sure, for a couple hours...but not when the power is out for days. When we had that ice storm, the first thing I did was bag my snakes up & put them under my
down comforter with me for warmth. (I was such a rookie that I thought surely the power would be back on by morning...) When I later told a few people that
I'd done that, they thought it was SO creepy? (obviously, they weren't snake keepers) Anyway, the morning brought "plan B", ice chests with jars of hot water.
