The Double Decker Cat Connector
This custom 12 ft wide x 4 ft deep x 8 ft tall freestanding catio is paired with a window catio and connected by an 8-foot enclosed tunnel, creating a seamless indoor-to-outdoor experience for curious cats. Built with pressure-treated lumber and enclosed in 1x1 black PVC-coated wire, the setup features a durable ribbed steel roof on the main catio and a clear polycarbonate roof over the window section, while the open-top tunnel provides a breezy pathway between spaces. Inside, spacious shelves, ramps, and a striking floor-to-ceiling natural scratch post offer plenty of enrichment, climbing, and lounging opportunities. With both a human access door on the main structure and an access point at the window catio, this thoughtfully designed system gives cats multiple zones to explore—like a private outdoor extension of the home made just for them.
