The Tunnel Retreat: Fully Enclosed Outdoor Catio With Tunnel & Grass Play Area

Give your cat the ultimate blend of safety and freedom with The Tunnel Retreat — a thoughtfully crafted Fully Enclosed Outdoor Catio With Tunnel that offers adventure, comfort, and connection to nature.

A custom-installed cat door leads from your home into a 16-foot-long tunnel, which gracefully elevates over walk paths and runs beneath the fence line to meet HOA requirements. This enclosed passageway connects directly to a spacious catio along the fence, allowing your cat to explore between home and yard with ease.

The catio spans 15 feet wide by 5 feet deep and includes two distinct areas: a 4 ft x 5 ft enclosed weather-protected space and a larger open-air section with a grass floor. Built using pressure-treated lumber and 1” x 1” black PVC-coated Critterfence, this structure balances durability with transparency and style. The enclosed area is topped with either a clear polycarbonate or color-matched metal roof to keep your cat dry and shaded in all seasons.

Whether lounging in the grass, perched in the tunnel, or tucked into the sheltered nook, your cat will thrive in a secure and enriching environment that seamlessly integrates into your outdoor space.
