Safe outdoor space for cats (designed to fit up against a wall on an outside deck / balcony). Approx 8 feet tall x 2.5 feet wide x 4 feet long (estimate). Enclosed on 3 sides with 3rd side left open to sit against a wall / window. We had it open onto a window for the cats to access from inside whenever the window was open. Top and bottom open to fit between balcony floor above and below. Adjustable to fit snuggly under above balcony with the "feet" attached at the 4 corners. One side has a door to access the inside. Has steps, ramp, perches, and hammock (could do with replacement after 1 year with outdoor weather). It's currently dismantled, all hardware for assembly included and the contact information (for assembly if you need assistance) of the person who built the catio, is available if interested. You will need a truck to transport the 4 sides. It is currently in storage.
