My chameleon is just over 6 months old now, and wow is he big! I have been preparing to move him to a larger cage. Currently he is in a 18"x18"x36" terrarium. It is pleanty big for him right now, but I know that in a few months, if he keeps growing at this rate he will need a new one. So he is my question, is a cage that is both long, AND tall better for adult chameleon, or does it not really matter how wide it is? The breeder estimated he would get about 20" long. Thank you!
