These are what I have been using for raising babies and juveniles. They work with some adults, provided you replace one end with screen,and screen the top. Most species that are very shy, and like to stay hidden, thrive in these things.
They can see light coming in, so they do not feel trapped, but they can still percieve it as being there - so they won't try to crawl through it like glass.
They also make great quarantine cages for all species. Usually, even less shy, mean animals will benifit from a safer-feeling, more enclosed cage for the acclimation period.
My friend Pete used these for most of his animals. his thoughts were that the translucent plastic alowed some light, but not details, through to the chameleon. The chameleon responds to these stimuli in the same way it woudl respond to being in dense foliage - it feels safe and secure. He kept large WC panthers and Veileds in them. It was totally weird, to go to his place, and see full grown, beautiful animals sitting in full happy colors, relaxed, not pacing, not trying to escape. It went against everything I knew.
I had a few problems. One, you had to maintain exact control over temps - because there was little in the way of gradients. Two, you couldn't get much natural behavior out of such a setup. Three, while the lizards themselves were healthy and happy, the cages looked like crap - and I keep few enough that that matters!
I just use them for my little guys. Once a day, push the cage furnishings aside, give it a good wipe, push them to the other side, wipe again - clean!
When they get older, and I have a horde of them to keep, I stab a few holes on one side, angle the cage, and use drippers right into it, on the fake plants. All the excess water just drains off.
The best thing, is when they're all grown up and gone, the cages stack neatly.
Or, you can use them for storing extra roaches.
