outdoor cat cube

Sizes vary widely. Small single-cat houses can measure about 17" L x 10" W x 32" H, while large enclosures can exceed 110" L x 47" W x 74" H. Many multi-level catios fall in the 60–70" height range with typical lengths around 62–70".

Common features include multiple tiers and activity platforms plus one or more enclosed resting or nesting boxes. Configurations range from 2-tier to 4-tier layouts, with roughly three to seven platforms and typically one or two private napping boxes.

Some feral cat shelters include full insulation in walls, roof, and floor (examples note ~0.6" Styrofoam) and may include a UL-tested waterproof heating pad with adjustable temperature and timer settings.

Roofs range from asphalt-covered or asphalt-plank options and polycarbonate panels to waterproof canopies or UV-resistant roofing. Designs often use sloped roofs or linoleum-style coverings to shed water.

Most include multiple access points—lockable cat doors or main doors—with dual/double-locking mechanisms on some models. Some also add PVC or curtain-style entry coverings for extra weather protection.

Many offer large access points—hinged or removable roofs, wide walk-in doors, or openable panels—so owners can reach inside easily for cleaning and maintenance.

Most listings require adult assembly. Some include the necessary hardware or basic tools; a few note no tools are needed because parts are pre-drilled and numbered.

Options include lockable, load-bearing wheels for relocation, modular designs that allow combining units, and removable panels or window attachments for connecting to a house window or pet door.
