I was just wondering if a 2w by 2l by 3h cage is big enough for an adult veiled Chameleon. Mines not a adult yet but I want to make sure that his cage is big enough when he get there. Lately he been really active and walking all over the enclosure, and I was just wondering if this is an early sign that he might need a bigger cage. I put in a lot of branches and things to climb on to try and utilize all the space. Any advice would be greatly appreciated.
