The Cascade Connection
The Cascade Connection is a custom multi-level catio system featuring an 8 ft wide by 4 ft deep by 8 ft tall freestanding main enclosure connected to two window-access catios—one at the deck level and another at the basement window—via dual 8 ft tunnels. Built from pressure-treated lumber with 1x1 black PVC-coated fencing and clear polycarbonate roofing, it includes shelves, ramps, and an internal divider for cat separation. The tunnels are designed with clearance for a golden retriever-sized dog, while human access doors on both the deck and ground-level catios make maintenance easy. This innovative setup blends functionality and enrichment, offering cats multiple zones to explore safely across different parts of the home.
