I'm kind of having the same problem you are with using a heat lamp/CHE. My solution to this is to spend the money and pick up some flexwatt and a nice thermostat. I'm finally ordering mine tomorrow. Yeah, bp's love to explore, so my guess is that she is feeling pretty good about her surroundings if she is moving around now. I would suggest getting one of those critter cage tops if you dont already have one. They have two built in clips in the back and a place for a lock in the front. Instead of a lock I just slide a golf tee in the holes and it works great. Good luck and keep us posted with anything new!
