I've been wanting another lizard for sometime now and I think a Mail would be a nice fit for me. I am going to be building a custom cage for him and was wondering if the dimensions I had in mind would suffice. I've read that a 4'x2'x2' cage is a nice fit for an adult uro. Problem is, the surface my cage is going to sit on is only 16 inches wide, but 7 feet long. So, I was wondering if a 5 or 6 feet long, 16 inch wide and 2 feet tall cage would be enough for him when he's full grown.
