We a huge advocates of catios over here! In ours we installed astro turf, a small planting section for real dirt and plants inside a modern and secure wire enclosure. The kings own the catio. The queens and kittens visit under supervision. The boys have free access to it from an interior room via a kitty door. The boys spend 90% of their time in the catio, by choice, instead of indoors. They sleep under the shade of the bushes and watch the rain while sitting on the windowsill. I could not imagine running my cattery or keeping boys happy without a catio. Please enjoy these photos of our precious fur kids in our catio!
