Thank you,

His cool side is at 75 while his warm side set at 90 but it showed 87.9, so we moved it to 92. His heat mat connected to thermostat controller. The humidity shows to be at 55 on the cool sie and 60 on the other end.
His cage is 36x16x18. And currently he is on paper towels. I have tried other substrates before, but it seemed that aspen was irritating him. He was eating medium size rats before going off feed. As of his weight I will get the scale to know for sure but it seems like he hasn't lost much with since he stopped eating.

I appreciate any help and advises.
