That looks great, and your cat clearly likes the perch ❤️
Maybe it’d like a hangout spot even higher up? I saw a video a while ago where somebody had made a “cat path” high up on their wall with some sort of cylinders maybe 15cm (6") in diameter and max 45cm (18") long wrapped in twine, at maybe 1m (3’) intervals or maybe even a bit more, so that the “path” led to a hangout spot high up in the corner of the room. Of course you’d need to build that in a spot where the occasional falling kitty won’t land on your collection of priceless Ming vases and live land mines, or your 99" 4K OLED TV.
Wouldn’t even need all that much material. Could maybe use pieces of PVC pipe for the “path”, twine, that hammoc or whatever platform you’d want to have, and then the… uh, what’s the word in English… fasteners? Everything you need to attach all that stuff to the wall.
