This cage looks like it was too much trouble for what it really is...
You can get a good cage for under 100 bucks and it'll last you forever... and it's a proper cage.
What you have currently is kind of an issue. I know on Reddit some people said it's kind of cool, inventive, etc, but I feel like an enclosure like this would not be proper for a chameleon.
If you're strapped for money, a chameleon really isn't a good pet to have.
A quick investment of 100 dollars or so gets you a nice cage that allows for what they need.
If the cage works for you, fine. But I see many issues with this.
Is there a front door? Would the chameleon be able to escape from the uneven gaps made by the tubs stacked upon each other?
To make the cage work, I'd make a screen door and a screen top, have the proper lights. If you can mist by hand that's fine but you need a place for the water to go.
Also even if you have fake moss, moss isn't a good thing to have either.
