Just curious, but around my area they're calling for severe thunderstorms which means power outages most likely and that got me to thinking. How serious of a problem would it be if your corn's viv lost heat for a long period of time (i.e. 12 hours or more)...obviously it depends greatly on the time of year (winter being the worst time for that to happen) but what should you do? Just leave the snake in her tank? Put a warm towl or something under the viv? Take them out to keep warm with your own body heat? Do nothing because the snake will be fine?...etc
In
The Corn Snake Manual, Kathy discusses brumation temperatures of between 45 and 65 degrees Fahrenheit, with occasional dips into the upper 30s. Of course, before brumation a keeper must try to ensure that all food items have been completely digested before beginning brumation. So if they've already been properly prepared for brumation, and the outage occurs during brumation, you probably don't have much to worry about. In the spring/summer/fall , you probably have nothing to worry about. My power went off for 18 hours about a month and a half ago, and most of my snakes' temps dropped to about 70. No problems resulted.
I don't brumate sub-adults or younger, so if this happened in the dead of winter (which isn't that much milder in CT than in Eastern Canada), I'd probably start thinking about chemically activated heating pads, or moving un-brumated animals to locations with alternate heat sources (ugh). I'd have a dozen or more snakes in this situation, and I love them, but I don't think it would be feasible to try and maintain their temps with my body heat!
A long time ago this happened to me in mid-winter, and I didn't do anything about it, despite the fact that I didn't brumate any snakes. They had no heat for about 24 hours, and the ambient temps in my home dropped into the forties. I had just arranged for a local pet store with a back-up generator to house my animals when the power was restored.
It would be interesting to hear from posters from cold climates who've dealt with this issue. But remember, you can't plan for everything, even if you wanted to. (There are meteors, nuclear threats, magnetic pole reversals... too many things to prepare for.)
