4. The Tunnel Catio System

If you want to offer your cats the fun of exploring without building a large enclosed structure, consider a tunnel catio system. These tunnels snake along the side of the house, across a yard, or between outdoor stations. Tunnels are typically built using wire mesh tubes or custom wood framed channels.

A tunnel catio can connect different parts of the property such as a window exit to a larger catio, or a deck to a garden space. Cats love running through tunnels because they mimic hunting and stalking environments.

You can attach viewing pods or bubble windows along the tunnel so your cat can look out more clearly. Adjustable platforms inside the tunnels can add extra climbing fun. This modular idea works especially well for homes with irregular yard layouts.
