Hoping your power has been restored. I use to get all panic'd everytime we had a power outage also - I ended up buying a portable generator to run my snake setups when this happens. The best $250 I ever spent just in peace of mind.

I also keep those portable hand warner things sold at Walmart in the sporting goods section. Those come in real handy when its just a short 4-5 hour outage.

Let us know what has happened since you last posted. Had your snake not just eaten - I think you would have been fine for hours since it is summer time but just eating adds another layer of concern. Been there and done that.
