I have a veiled chameleon he has a cage that is 3' long x 1 1/2' wide x 4 1/2' tall. He's been in there for 4 months, and this past 2 weeks or so he's been really stressed out. He has a temperature gradient of 93-108F at the basking spot, 80-85F at the top, and 72-75F at the bottom. Humidity is 60-80%. Here are pictures of the set up(bottom and top) and him.
