What is the Cat Sìth?

The Cat Sìth is often described as a large black cat, roughly the size of a dog. Its fur is black with a white spot on its chest. The cat’s eyes are said to glow, adding to its presence. When threatened or agitated, its posture becomes defensive, with its back arched and fur standing on end. The Cat Sìth is often associated with supernatural qualities, moving silently and appearing as a guardian of the ancient places it is believed to inhabit.
The Cat Sìth differs from an ordinary domestic cat. While domestic cats are generally seen as affectionate pets, the Cat Sìth is an otherworldly entity that can walk on its hind legs when not observed. Unlike regular cats, which move with familiar grace, the Cat Sìth is associated with fairy lore and has the power to steal souls.
“The Cat Sìth is not merely a creature of flesh and fur, but a spirit woven into the fabric of Celtic mysticism.” – Anonymous
The Origins of the Cat Sìth
The Cat Sìth is a figure in Celtic folklore, particularly in Scottish and Irish traditions. The name “Cat Sìth” comes from the Gaelic language, where “cat” means cat and “sìth” refers to supernatural beings or the fairy realm.
In Celtic beliefs, animals were often thought to have connections to the spirit world. Cats, in particular, were seen as capable of moving between the natural and supernatural realms. The Cat Sìth is closely tied to the Scottish Highlands, where it is said to roam the land. The area’s rugged terrain and long-standing traditions helped the legend of the Cat Sìth to develop. While the creature is more widely recognized in Scottish folklore, in Irish myths it is known as the Cat Sí. In both traditions, the Cat Sìth is linked to the fairy folk and is seen as a guardian of the supernatural.
One well-known legend about the Cat Sìth is its ability to steal souls before they move on to the afterlife. To protect the soul, families would perform rituals like the Fèill Fhadalach (late wake) to keep the cat away from the body. During Samhain, which later became Halloween, it was customary to leave milk offerings for the Cat Sìth. If the cat accepted the offering, the household would be blessed, but if not, it would be cursed. Some variations of the tale suggest that the Cat Sìth is actually a witch who can transform into a cat up to nine times. After nine transformations, she remains a cat forever.
Early mentions of the Cat Sìth were found in oral traditions and passed down through generations. These stories depict the Cat Sìth as a powerful figure capable of influencing human lives. In Scottish folklore, one of the earliest literary references to the Cat Sìth appears in the English folk tale “The King of the Cats,“ where a man witnesses nine black cats with white spots on their chests carrying a coffin with a crown on it. This story highlights the Cat Sìth’s connection to death and the supernatural. In Irish folklore, the Cat Sìth is known as the Cait Sidhe and is also linked to the fairy folk. The Cait Sidhe is often associated with the festival of Samhain, where it was customary to leave out offerings of milk for the fairy cat.
The Folklore Surrounding the Cat Sìth
The Cat Sìth is surrounded by various legends and tales. Here are some of the most prominent stories:
- The Tale of the Bewitched Farmer: A farmer encounters a black cat while working in his fields. Unlike other cats, this one follows him everywhere, giving off an unusual feeling. Suspecting the cat is a witch in disguise, the farmer traps it. Once caught, the cat changes back into a human, revealing herself as a witch. She curses the farmer for his actions.
- The Guardian of the Fairy Folk: In this tale, the Cat Sìth is protecting the fairy realm, guarding it against humans and other creatures. It is said that the Cat Sìth can summon other fairy beings to help create a barrier around the fairy kingdom, ensuring its safety and peace.
- The Tale of the Cursed Cat Sìth: A Cat Sìth was once a family pet, loved and cared for by its owners. However, a witch cursed the cat, turning it into a Cat Sìth with a vengeful nature. The once gentle cat became a spirit, haunting its former home and bringing misfortune to those who lived there.
- The Cat Sìth and the Highland Warrior: A brave warrior encountered a Cat Sìth during a night patrol. Rather than fleeing, he stood his ground and communicated with the creature. Impressed by his courage, the Cat Sìth revealed secrets of the fairy realm and granted him protection.
These stories, along with many others, contribute to the presence of the Cat Sìth in folklore.
Modern Interpretations
Some modern interpretations suggest that the legend of the Cat Sìth may have been inspired by the Kellas cat, a hybrid of domestic cats and wildcats found in Scotland. The Cat Sìth has influenced various superstitions, such as the belief that black cats have nine lives, as well as their association with Halloween and witchcraft.
The legend of the Cat Sìth has appeared in various forms of media, including books, movies, and video games. For example, it has been featured in the Final Fantasy series, where it adds an element of Celtic mythology to the game’s world.
Cait Sith first appears in Final Fantasy VII as a fortune-telling robot controlled by Reeve Tuesti, an employee of Shinra Corporation. Cait Sith rides a giant stuffed Mog, a creature from the Final Fantasy universe, and uses a megaphone to give orders. Initially, Cait Sith joins Cloud Strife’s party to spy on them, but as the story progresses, he becomes a loyal and helpful member of the group.
In modern stories, the Cat Sìth has been reimagined in different ways. You can find it in fantasy books, kids’ stories, and even some horror tales. These newer versions mix the old folklore with fresh ideas, keeping the Cat Sìth a long-lasting character.
In the anime Ao no Exorcist (also known as Blue Exorcist), a character named Kuro is inspired by the Cat Sìth. Kuro is a black cat with two tails who serves as a familiar to the main character, Rin Okumura. Originally, Kuro was the familiar of Rin’s mentor, Shiro Fujimoto, until Shiro’s death. Kuro has the ability to transform into a larger, more powerful form known as a Nekomata, and can communicate telepathically with demons. This character draws on the shape-shifting qualities of the Cat Sìth in its portrayal.
While the Cat Sìth doesn’t often appear directly in movies, its mythological background has influenced fantasy and horror genres. For example, films like Coraline feature mysterious cats that lead characters through strange worlds, reflecting the magical and otherworldly traits of the Cat Sìth.
