@steve wow, that's awesome. My daughter wanted to do something like this for our cat, but I didn't have a visual. Our cat has literally broken out through screens three times and is capable of opening sliding or unlatched screen doors. We have a lanai with screens, so we made a 2x4 walking path up high. Two cat trees on either side. The cat isn't as interested in it anymore, prefers to sleep at ground level, seeking cool surfaces. We never interact with the cat when he's in a sleeping bed, and there are several. Thanks for sharing those pics, it has given me some ideas. Great cat pix!
