That is how I currently keep one of my chameleons. I have two ficus that I linked together with some fake vines. He is in my bedroom with all the doors closed. Most of the time he stays there but every once and a while I find him on the curtain rod or on the top of my shelf with my teddy bear. I also keep my room very warm and have a basking light and 48 inch florescent uv lights and a dripper hanging from the ceiling over the trees. I would not suggest putting him in a high traffic area. If he gets off the tree, you wouldn't want someone to step on him. Whenever I go into my bedroom I always make sure to find him first.
