Manx cat
Regardless of the genetic and historical reality, there are various fanciful Lamarckian folktales that seek to explain why the Manx has a truncated tail. In one of them, the biblical Noah closed the door of the Ark when it began to rain, and accidentally cut off the tail of the Manx cat who had almost been left behind. Over the years a number of cartoons have appeared on postcards from the Isle of Man showing scenes in which a cat's tail is being run over and severed by a variety of means including a motorcycle, a reference to motorcycle racing being popular on the island, and an update of the Noah story. Because the gene is so dominant and "invades" other breeds when crossed (often without owner knowledge) with the Manx, there was a folk belief that simply being in the proximity of a Manx cat could cause other breeds to somehow produce tailless kittens.
