Ferret Nation Add-On Unit Small Animal Cage - Expands Living Space

Our review of the Ferret Nation Add-On Unit (model 183) finds it is a practical expansion for owners who already have a Ferret Nation cage and need more room for small animals. The biggest reason to buy is simple: it reliably adds 36in x 25in x 24in of additional, climbable living space that integrates with models 181 or 182, giving pets more room to explore without replacing an existing setup. The add-on keeps the same thoughtful features found in the original cage, including full-width doors and critter-proof latches, so it feels like a natural extension rather than a compromise.

Key Features

• Increased living area: Adds 36in x 25in x 24in of additional room so pets have more floor and shelf space to play and rest.
• Model compatibility: Designed specifically to stack with Ferret Nation models 181 and 182, making expansion straightforward for current owners.
• Full-width doors: Double full-width doors provide large access points that simplify cleaning, feeding, and interaction with pets.
• Safe climbing space: 0.5in vertical wire spacing allows natural climbing and exploration while keeping small animals secure.
• Included accessories: Comes with one leak-proof pan, one adjustable shelf, and two ramps with soft covers to protect sensitive feet and increase enrichment.
• Tool-free installation: Installs on top of an existing unit without tools and uses critter-proof latches for secure stacking.

Who It's For

The add-on is ideal for ferret owners or families with similarly sized small animals who already own a Ferret Nation model 181 or 182 and want to expand living and play space without buying a whole new cage. It suits people who value easy access for cleaning and feeding and who want durable, climbable wire spacing for active pets.

It is less appropriate for someone starting from scratch who does not own a compatible base unit, or for owners of much larger species that need taller or heavier-duty enclosures; in those cases purchasing a full double unit or a different habitat may be a better choice.
