I am using aspen bedding... and have no legit way of controlling the uth... she stays under her log on the warm side where the uth pad is... so I assume it is fine... because when I originally moved her into her now cage she refused to be on the hot side and once i got some under tank ventilation she starteed going on it (aka it was too hot and she couldnt be over there)... hm... shoudl I not use aspen bedding? when I get enough money I am going to buy a thermal heat sensor thing... where its point and tells you the heat of the area.. but I am broke right now... literally... so.. I am just going by the humidity on the cage walls... and how damp the bedding looks... shoudl the cage be humid.. but not the bedding... like the ambient air humid but not the actual bedding?
