Ok, everything I do is about Catios, Catio cat enclosures, Window catios, and Outback catios. Outdoor Catios, Catios in DFW, and all North Texas. This all started with a friend that had four cats, and she said she had one that always wanted to go out. 2 were 19 years old. They wanted to go out all so. I don’t think that she or I knew what a Catio was. I just made a chicken wire box outside a window out of scraps that I had and the way my first Catio was. She found out it was a catio, 3 of the four cats liked going out. It was just one level—a square box. I will try and post a photo of it. Looking back on it was kinda nice. We both felt strongly about not letting cats get in the bushes and take out our songbirds.
