To kc261, I use a heat mat with two books on both sides of the screen top with tape on half of the screen(sticky side pointing out of the cage, not in). I am using a flukers hydrometer and thermometer combo and it usually says 77.6 degrees and 60% humidity. The hot spot measured was like 95 degrees with like 45% humidity. I will try the crumpled newspaper but when he starts eating, do I have to leave it there? Maybe some greenery will help because I can leave it once he eats again.
