The days are controlled by a timer that goes off at 730pm I leave the cold side with a small 25w night on at all times just to keep the head somewhat warm I'm in jersey and its cold here now. I have 2 thermometers 1 on each side and I use a heat gun and they are within the same range. The other day when my apt heat kicked on she was a little dehydrated she had the sunken eye thing going on it lowered the humidity to 30 but after she drank and I misted it returned to normal. I called a vet too and he said it seemed ok. I just want her to eat it's been about a week and a half I had her on a 5 day feeding schedule and she has never refused for me over 5 months now so just concerned why now
