There are various mutations affecting the tail and in 1940 American zoologist Ida Mellen wrote of oddities in cats' tails including kinked, bobbed, curled and even double tails. Curly tailed cats were known in China in the 12th Century (probably bobtails) and ringtail cats were known in the USA sometime prior to 1940. In 1868, Darwin wrote in The Variation of Animals and Plants Under Domestication "Thropughout an immense area, namely the Malayan archipelago, Siam, Pegu, and Burmah, all the cats have truncated tails about half the proper length, often with a sort of knot at the end." Tailless and cats have occurred periodically through random mutation. They have been reported in Bosnia, Burma, China, Crimea, Java, Malaya, Denmark, Nova Scotia and Thailand though some of these will have been bobtails. Bobtail cats occur throughout Asia and into Russia, with more recent mutations occurring in the USA. In a 1949 study, Searle found no kinked tails in London cats
