The Den: Custom Pressure-Treated Catio with Tunnel Access

Give your cat the freedom to roam, climb, and play — all from the safety of your backyard. The Den is a spacious, fully enclosed Custom Pressure-Treated Catio with Tunnel Access. It’s designed to expand your cat’s world while adding charm and function to your outdoor space.

This freestanding catio measures 12 feet wide, 8 feet deep, and 8 feet tall. It provides plenty of vertical space for climbing, lounging, and exploring. One of its standout features is a 15-foot tunnel that connects the catio to our clients home. Since the tunnel is raised high enough to walk under, it keeps your yard open and easy to navigate.

We built The Den with durable, pressure-treated lumber to stand up to weather and time. A clear polycarbonate roof shields your cat from the elements while letting in sunlight. The entire catio rests on a deck platform, which improves stability and keeps moisture out. Inside, your cat will find ramps and shelves that turn the space into a multi-level playground. Plus, a full-size access door lets you step inside for cleaning or playtime.
