Hi,I got this on Ebay today, it is the same floorsize as a Hamster Heaven but obviously much taller. The label says imac and I believe it is a ferret or rat cage, same bar spacing as the Hamster Heaven. I think it originally had tubes coming off the shelves but they were big ferret sized tubes. there are 5 doors in total. I can't find anything like it on the net does anyone know what this cage is called? I only paid £16 for it so I think I got a bargain.
