The Isle of Man Shorthair is basically a tailed Manx Cat and shares it history with the Manx Cat Breed. The precise date of the Manx cat is quite unclear, but their association with the Isle of Man is known worldwide.

The origin of the Manx cat is diluted with folklore and urban legends, from the genetically impossible theories, to romantic folklore of tailless cat survivors swimming to the shores of the Isle of Man and eventually mating with the local domestic cats in the Island. There are many other various stories about this cat breed’s origin, but one thing is sure, tailless cats much like the modern Manx cat has been appearing all over the Isle of Man as early the early years of the 19th century. These cats were originally called “stubbin”, a local word to describe the cat’s unique tail-less appearance.

There was a random and spontaneous genetic mutation among the island’s domestic cat population which resulted to some cats having no tails, or having just a short knob for a tail or having very short and stumpy looking tails. These eventually became the ancestors of the modern Manx Cat breed. At the same time, semi long-coated cats with the same different tail varieties also appeared. This eventually became the ancestors of the modern cat breed. The Isle of Man’s domestic cat population was soon filled with longhaired tailless cats or Cymric cats and longhaired tailless cats or Manx cats. What is not mentioned on other accounts of the history of the Manx and Cymric is the appearance of cats that within the island that have full set of tails and comes in both short and long coat varieties. These cats are different from the Cymric and Manx not just in because of their coats or tails, but because they lack the genetic expression that made the Manx, and eventually the Cymric as tailless cat breeds. These type of fully tailed cats from the Isle of Man eventually became the ancestors of the modern Isle of Man cat breeds.
