15 Free DIY Catio Plans That Are Perfect For The Outdoors (With Pictures)

Many of us keep our cats indoors for safety reasons, but it’s also nice to enrich their lives by allowing them outside to enjoy the fresh air. Building an outdoor cat enclosure is the perfect solution. Your cat is safe from predators (or being the predator), but they can still spend time outside in an enclosed environment.

We’ve reviewed several designs, referred to adorably as “catios,” and rounded up our top DIY catios. From large enclosures with tunnels and platforms to small enclosures that sit next to a window, you will learn how to build the ideal catio for your furry friend.
