The ferret nation is assuredly the most popular cages for ferret owners, with its high build quality, ease of maintenance and customizability it is easy to see why.

The ferret nation allows its owners to purchase additional sections which can be added on to extend the enclosure even taller, and though not suggested by the manufacturer, it is possible to connect them width wise creating a safe and large liveable area for many ferrets.

While most "ferret" cages are only suitable for one or two ferrets, 4 or more can safely live in this enclosure (when using the two story.)

Some owners have found good deals on used Critter nations which are virtually the same cage.
