I am trying to get a pair of jacksons chameleons. I know they like it cooler than most because they live in the mountains. My problem is my lizard room gets to be warm (around 80-90 degrees) so I have looked into cooling systems but not having good luck. The repti cooler by zoomed only lowers temps by 10 degrees. Is hot temp really lethal to jacksons? Does anyone have a good reptile cooler?
