Each Catio is designed to be made from a wooden frame, escape-proof wiring, and cedar shelves for cats to lounge on. The boxes can attach to a window or door leading outside, allowing your cat to wander in and out without putting itself in harm's way (or posing a threat to wildlife).
"Cats naturally want to be outside where they can breathe fresh air and experience the sights, sounds and stimulation of the natural world," the Catio Spaces website reads. "A catio, an outdoor cat enclosure or 'cat patio,' is the purrfect solution to solve the indoor/outdoor dilemma."
Plans for DIY catios you can assemble at home range in price from $40 to $70 (materials not included). You can order and download yours today, with 10 percent of your purchase price going to an animal welfare organization.
