So, just leave her a lone except for feedings? I can do that.

I realize that the temperatures are a bit low, but I'm not sure how to raise them. I'm using an 8-watt undertank heater AND a 50-watt Tight Beam bulb, and the temperatures posted are the normal. I have a 75-watt Tight Beam bulb; should I switch to that? I'm also covering half of the top (it's a hinged wire closure) with triple-layered aluminum foil to help keep the heat and humidity in, but it's not working as well as I hoped for.

As to her age; I'm not sure. She was sold to me as a hatchling, and was about 18 or 20" long when I got her on January 9th. She doesn't ball up however; she just jerks away and retreats to her hide.

Feeding her was a success; I fed her live and she made a perfect face strike with three coils wrapped around. The mouse didn't squeal and it didn't bite, but she did eat it upside down.
