I knew one cat (he was older than me at the time), it was a topological cat-antipod. Everyone knows that the Khachas love to play with cloves (spades, threads, etc.).In the 70s, who remembers, were fashionable such abajures, made by chaotic wrapping of something fibrous type of multi-colored threads on a half-meter sphere and fixed with something glue-like. This is a fairly tough empty bowl with a hole. We have such a valsso in Chulan. Kshak quickly wished that his monk would be used in the monocycle catch when he got inside. Perseus in particular. Moreover, it was not a chaotic rolling of the fool, he moved deliberately, bypassing obstacles!
