1. The Window Box Catio

A window box catio is one of the simplest and most space saving catio options. It is perfect for small homes, apartments, or condos where outdoor space is limited. This type of catio attaches directly to the windowsill, allowing your cat to step right into a secure outdoor perch.

A sturdy wooden frame covered with wire mesh or metal fencing creates the structure. Inside, you can add platforms or perches so your cat has a comfortable place to lie down or observe the outdoors. This type of catio gives your cat fresh air and sunshine without the need for a yard.
