You lucky duck, right next to Kurt. I see he posted before I did. Since I have moved all but my Dumpy into the back bedroom I worry not at all about heat. It's warmer in here and no drafts. My redfoot tortoises are crawling around the floor and not trying to hibernate either. I turn the lights on in the a.m. and off in the p.m. mainly for my benefit in seeing the miniature jungles.
