The Mid West Ferret Nation Cage is specifically designed with unique, rich features that both ferrets and their owners will love. The Ferret Nation Cage contains numerous attaching points for accessories, including hammocks, tubes, and toys (sold separately). The swinging, locking ramps are appropriately angled with reversible Happy Feet covers that are specifically designed for ferrets. The cage is a sturdy square tube frame that is constructed with 12 gauge wire, with a platinum gray quartz hammertone finish that is extremely attractive and durable. And, the new Ferret Nation cages (Models 181, 182, and 183) are now compatible with the Critter Nation cages.
