How many platforms does the 55 Inch Catio Oneluck OK-387D-FBA provide for a multi-level walk-in space?

You need a 41-inch by 41-inch level area for the base and should measure your available ground space before installation.

The Oneluck OK-387D-FBA catio includes 6 platforms for vertical movement

The Oneluck OK-387D-FBA features a load-bearing metal frame structure that supports 6 plastic platforms and a side skylight. We selected this model for our full review because it provides a high platform count relative to the 41-inch footprint. Because cats rely on verticality to feel secure, having enough levels ensures they can escape ground-level disturbances. If you choose a model with too few levels, your cats may feel trapped in a single zone, potentially leading to stress or restricted movement.

Comparing the Oneluck OK-387D-FBA to Other Options

The Oneluck OK-387D-FBA is a practical choice for owners who prioritize a high platform count and a metal build for durability. Buyers seeking a more compact footprint or a wooden aesthetic might prefer different materials, as this model uses a metal frame and plastic platforms. If you require a custom-built hardwood structure with specific rot-resistant timber, you may want to look at professional-grade cedar options instead of mass-market metal units. This model is ideal for those who want a ready-to-assemble, multi-level play area that can handle 1 to 3 cats.
