The power is out in my neighborhood due to some maintenance the electricity company is working on. The outage began at 7 am and they said it will *hopefully* be back on by 10 pm. It's rather inconvenient for me obviously but I'm more worried about my invertebrates! I keep a variety of animals with different temperature requirements but I guess specifically I'm asking about my slings. I have a C. versicolor and a GBB, both at an inch. It's about 57 in the room right now and the low tonight is 39F. I am trying to get creative as to how to warm my room, one idea involved a Sterno stove... Should I be that worried about one cold night?
