I definitely did my research before going ahead with this project. This is bigger than the reptibreeze you can currently buy. The width is 24” x 28”. The height is 50” after gutting out the inside. Chameleons like to climb up and down instead of side to side. This has plenty of height and width for an adult chameleon. Plenty of shaded spots, basking spots, sleeping spots and climbing room. If I every feel that my panther needs more room later down the road, than I won’t hesitate to build another one haha
