I have another thread under Housing, too. I have reduced my cage (4'x2'x2') to half of its height because I was afraid (and some members here agreed) that it was too large and Baron (my cham) was not finding his food.
Another issue I have is that I made a cup feeder (carved-out old milk container w/ screening) to hold the crickets, but they seem to climb and jump out of his regardless.
Additionally, when I bought the cage, it had wire mesh for its walls. I wasn't thinking when I bought this that the crickets would be able to escape- which many did- so I reinforced the wire with additional window screening, so they can not escape. When I cut out the screening, I left enough along the outside of the framework so that I could seal the edges with tape. Then I used cable ties to attach the screening at the four corners of every side to make it tight.
Other than those issues, he seems to be doing okay. He is a bright green when "hiding" in the leaves and branches, but then turns a few shades darker when he starts to crawl outside the safety of these plants. Baron is very shy when I'm around and dips back into the leaves when I go to check-up on him. His stool is solid and white/black.
I hope to post more pictures of him, but he is camera shy. Once I get the camera activated, he is already trying to hide. lol
