The consensus seems to be that the minimum size for an adult Veiled cham is 2'x2'x4'. This is the cage size I have and it seems big at first, but I can certainly see how an adult could easily use more. 3' will be too short.
: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.
