buy one ive just bought one from ebay for my boys ferrets,it comes today flat-packed,i could have built one ,but ive never got the time with my two young boys,the new one we are getting,has a pull out plastic tray to save the wood from rotting,but the hutch is going in our massive log store ,once in there we shall open the doors for them to run around all day,and that's 5x7 so it will be great for them,post you some photos when I get the hutch,have a look on ebay hope you get it sorted,nice and big keep them happy
