Regular thermometer? Not sure what you mean by that. I would go to WalMart and buy a digital thermometer/hygrometer in the hardware section. It's only about $12 and made by Accurite.


You didn't say, do you have at least two hides in there, one on the warm side and one on the cool side?

Your low temps probably contributed to the RI (if that's what he has, but your vet will tell you for sure when you take him in on Monday).
