Thanks for the info. I've removed some foil I had on the top of the tank that I was using to adjust humidity. This has brought he cool side down to 82 degrees and the hot side down to 90 Degrees, Humidity dropped a little but still above 50%. I will make the switch to small rats this Tuesday when I feed him. Do you think that the cool side temp is making him jumpy after putting him back in his enclosure?
