I once did two weeks of cat-sitting for a neighbor who had half a dozen cats in his apartment. He also had a plethora of hanging plants, some of them affixed to the ceiling. For almost the whole time, the cats ignored the plants: but then they went into full Tarzan mode. Oh, what a mess! Hanging from the overhead light fixtures, too. It was as if they had suddenly discovered how to fly and were making the most of it.
Sort of like the cats in this video.
