The Cedar Skyline: Large Freestanding Backyard Catio on Deck with Tunnel Access
Give your cat a spacious outdoor retreat that feels like a natural extension of your home. The Cedar Skyline is a large freestanding backyard catio built on an existing deck, designed to maximize both space and enrichment while maintaining a clean, integrated look alongside the house. With thoughtful tunnel access and a wide, open layout, this build creates a safe, engaging environment where cats can explore, climb, and relax just steps from indoors.
Measuring 12 feet wide, 6.5 feet deep, and 10 feet tall, this enclosure offers a generous footprint that balances openness with structure. Built from cedar lumber and finished in a rich walnut stain, it delivers long-lasting durability with a warm, elevated aesthetic. The roof is carefully sloped to mirror the home’s existing pitch, creating a seamless visual flow, while 1” x 1” black PVC-coated welded wire fencing ensures safety without compromising visibility. Although constructed on top of the existing deck, the design maintains a freestanding feel for flexibility and stability.
Inside, the space is designed for both activity and comfort. Shelves and ramps provide easy movement between levels, supported by a floor-to-ceiling cedar scratching post and two cozy cedar cat cubbies for rest. A custom-built tunnel, 2 feet wide and extending from a wall-installed cat door connects the home directly to the enclosure, gradually rising in height as it enters the catio and featuring a built-in bench top for added functionality. The result is a dynamic, enriching outdoor space that gives cats the freedom to explore while staying completely safe and connected to home.
