I got this 4x4x2 cage for a couple of my tegus, but I'm not sure if they are big enough for it yet. The all american is I think 14" and the bnw is about 18". I am just wondering if they are going to be overwhelmed with the size, and how hard it is going to be to find them/ catch them for feeding. I might just go for it, and if it proves to be a problem, put them back.
