Interesting! But they'd all try to get into it together, and those suction cups would give way. Look at my earliest pics, when I lived in a small apartment and my cats couldn't go out. I had a window box that looked sort of like a window AC unit, and that was their outside access.

Floppy got frisky and made a rare trip up the wall system. He went all the way to the long shelf over the window, about 6 feet up, but by the time I grabbed the camera, he was back to the lower shelf.

I also couldn't find it but I've found pics from Wayne (Batman) posted a few days ago. Do you remember him ? Seems that Batman went over the rainbow bridge some time ago.
