Thanks for the advice. I turned down the temp on the thermostat and now the hot spot is 87-88, ambient is down to 79-80. The floor of the cool side is 79. I'll see how that goes and maybe knock the setting on the thermostat down another half a degree or so.

Last night I offered a thawed hopper mouse, but he showed no interest. A couple of tongue flicks as all. I even nudged his nose a bit with the mouse and still he dind't react. I'm going to wait until Sunday and offer again.

Also he seems really sluggish. He's only moved between two spots that are a couple of inches apart. Perhaps he's been a bit to warm. This normal for a boa?

Please keep the advice coming. Any and all suggestions are welcome!

I have a tendency to stress out over these things. My fist snake was a corn and I was so wrapped up in her well being that my bald-spot got bigger!
