When I used to have two iguanas (one was about 1 foot and half w/o tail the other was probably over two feet w/o the tail) we had a their big ass home built cage on wheels and put the whole thing outside during parts of the summer. One time the big one worked his way through the metal wiring and they got out. We broke down the cage thinking they were gone, and a couple weeks later I got a call from a friend who lived on the oppositive cove of the lake from me saying he caught my lizard.
Him and his friends saw the lizard up in a tree, caught it and then found out it was mine and I got him back.
Never found the smaller one though.
