How's old your Cham? The cage looks way too small for him/her. As they get bigger they require MUCH more room when they are younger. He looks a little cramped up in there. Just making a suggestion, you Chams health can suffer if he is not in the proper surrounding. I sould suggest if you don't want to buy one just make a cage about 2x2x4 at the minimal. The higher you can make the cage the better, they need a huge amount of space to climb.
