Thank you all for the great input. I will water his cage a bit less, was doing everyday, will switch to every other day to lower the humidity. I did get my instrument at Walmart. I have it located right in the middle of the cage to monitor my stats, so I can assume that the cool side is a degree or so cooler, and the warm side a degree or so warmer.

I have place a couple of things on the outside of his cage around where he usually hides to make it even more secure for him, but he seems to be doing fine.

Now, I should probably check around the site more for this question, but if I freeze a mouse how long does it take to thaw the mouse.
