I'm always amazed at the things people do with their cats. I wouldn't even try any of it with my girls; they'd filet me. As it should be.
Did you see this one? There's a shorter version, but I like this because of the addition of other engineers and cats, plus one "cat". Also, his really bad German-Swiss accent. And... the really dorky engineer sequence at the beginning, "Free Aspect Ratio".
I have a feeling that they might become more nimble with practice. When I take our terrific two out for walks, they both hone their coming down out of tree skills. They are both getting much better at it, and they learn from each other.
