The cat-sìth is a fairy creature from Celtic_mythology, said to resemble a large black cat with a white spot on its chest. Legend has it that the spectral cat haunts the Scottish Highlands. The legends surrounding this creature are more common in Scottish folklore, but a few occur in Irish. Some common folklore suggested that the cat-sìth was not a fairy, but a witch that could transform into a cat nine times. The cat-sìth may have been inspired by the Scottish wildcat itself. It is possible that the legends of the cat-sìth were inspired by Kellas cats, which are a distinctive hybrid between Scottish wildcats and domestic cats found only in Scotland (the Scottish wildcat is a population of the European wildcat, which is absent from elsewhere in the British Isles).
