My cats absolutely love this Catio. It’s large enough for multiple cats and I was able to relocate all my cat potties outside. The only thing I didn’t realize was that the roof has to attach to a wooden strip attached to the siding or wall at the rear. Be aware that if there’s a window along the wall at the height of the wooden strip there will be some modifications needed to ensure attachment. Also the roofing is clear which makes it hot during summer so I had to put faux leaves over the top and sides to make it cooler.
