I have a free ferret cage (pic available upon request). I no longer need it and it is in excellent condition. It is completely open on top (to add another cage) and is open on the back right corner to accomodate a cage below (or you could close if off if you wanted to make it the bottom cage). IT has two landings and two ramps and two doors (one small and one large). It measures 20 X 20 X 36 inches. Located in the San Jose area. Free for you to pick up if you are in that area!! deb [Posted in FML 5828]
