Small Space Catio Ideas

1. The Window Box Catio

A box-style enclosure that mounts outside an existing window. Your cat accesses it through the window, sits in the enclosed box, and gets fresh air and outdoor stimulation without being able to escape. No yard required. Works in apartments, condos, and any home with an accessible window.

  • Best for: Apartments, small homes, cats that primarily want a perch with a view
  • Approximate size: 24–48" wide x 18–24" deep
  • Installation difficulty: Easy — most mount with tension rods or window frame pressure, no drilling

Best budget pick (~$80–120): A basic wood-frame window catio with wire mesh sides. Functional, lightweight, and easy to install.
