I personally think no cage can be too big. These little guys live to explore. My concern about the cage is all the wire platforms for their little feet to get stuck in and cause an injury. You might as how big is the spacing between the wires, i didnt see anywhere it says that. The slide out pan is a big help. I built my own cage in a few hours, i didnt make it have a slide out pan, i just vacuum it all out with a shop-vac, ( while the chin is out ), then clean my pan with a mild soap and let it air dry. If you wish, i can find the link i found how to make your own cage in and link it to you. I spent about $140 to build mine, and it is awesome.. ( the chin thinks so anyways )
