You mentioned screen cages only... I am about to build an in wall cage in my living room for some type of display animal. I had not even considered a chameleon until I saw your beautiful specimens. The cage can be up to 3ft tall x 6ft long x 2ft deep. The front of the cage will have to be glass or plexi and the back will have to be black pvc on passing door tracks. The sides and top could very well be screen if necessary. Do you think this would be sufficient for a cham, or should I go with a different reptile? (I have a great deal of experience with reptiles, but none with chameleons.)
