Koshin-yama Yamaneko

Tradition / Region: Japanese mythology
Alternative names: Koshin Mountain Wildcat, Koshinzan Yamaneko
Category: Cat

The Myth

The Koshin-yama Yamaneko was a gigantic wildcat that had lived for hundreds of years, growing to the size of a calf and gaining immense supernatural powers. Its face resembled that of a raging tiger, its mouth stretched to its ears and was redder than blood, its fangs were as white as swords, and although its body was human-like, it rode a grotesque horse formed from an ancient tree spirit. Its eyes shone like torches, and after revealing its true form, they gleamed like mirrors while its whiskers resembled snowy pampas grass. It could command the beasts of the mountain, ride tree spirits as horses, speak human language, and even had the mountain and land gods as its servants.

Seventeen years before the events of the story, the local samurai Akaiwa Ikkaku climbed Mount Koshin to prove his bravery. Unknown to everyone, he was killed and devoured by the monstrous wildcat. The creature stole his clothes, assumed his appearance, and descended from the mountain to live in his place. It sought to possess Ikkaku’s beautiful second wife, Madoi, whose life was eventually drained through sleeping with the disguised monster. The false Ikkaku then continued living among humans, abusing his eldest son Kakutaro while living with the wicked woman Funamushi, whose greedy nature allowed her to remain unaffected by the monster’s supernatural influence.

Years later, the Dog Warrior Inukai Genpachi arrived in the region while searching for his scattered companions. After hearing rumors of a monstrous wildcat living on Mount Koshin, he became lost in the mountain during the night. There he encountered the mysterious horseman whose blazing eyes pierced the darkness. Genpachi fired an arrow that struck the rider’s left eye, forcing the monster and its attendants to flee. Soon afterward, he met the ghost of the real Akaiwa Ikkaku, who revealed the truth about his murder and begged Genpachi to save his son Kakutaro from the impostor.

Genpachi descended the mountain and uncovered the schemes of the false Ikkaku and Funamushi. They falsely accused Kakutaro’s wife Hinaginu and eventually demanded that her unborn child be sacrificed to restore the monster’s wounded eye. Rather than allow others to suffer, Hinaginu stabbed herself in the stomach. At that moment the sacred Jewel of Propriety burst from her body and flew across the room, shattering the chest of the false Ikkaku with divine punishment.

As the battle continued, the false Ikkaku rose again, cast aside his human disguise, and revealed himself as the monstrous wildcat. Declaring that only by tearing apart his enemies, drinking their blood, and devouring their flesh could he preserve his supernatural power, he attacked Kakutaro and Genpachi. After a fierce struggle, Kakutaro severed the monster’s hip, brought it crashing to the ground, and finally pierced its throat, avenging the death of his true father.

Although the monster’s body was burned, strange illnesses and supernatural disasters continued to plague the region. Its ashes were eventually gathered and reburied beneath a cat mound, appeasing the wildcat’s lingering curse. Afterward, peace returned, and it was said that rats no longer came near the surrounding fields.

Yule Cat

by

Tradition / Region: Icelandic Mythology
Alternative names: Jólakötturinn, Jólaköttur, Christmas Cat
Category: Cat

The Myth

The Yule Cat is a gigantic, vicious cat that prowls the snowy countryside during the Christmas season. It is said to lurk outside homes searching for people who have not received new clothing before Christmas Eve. In some versions of the legend, it devours those unfortunate people, while in others it steals and eats only their Christmas food. The Yule Cat is closely associated with the ogress Grýla and the Yule Lads, and is commonly regarded as Grýla’s fearsome pet.

According to Icelandic tradition, the Yule Cat appeared each Christmas to punish laziness. Farm workers were expected to finish processing the autumn wool before the holiday. Those who completed their work were rewarded with new clothes, while those who failed received nothing. Anyone without new clothing risked becoming the Yule Cat’s next victim.

Later traditions connected the beast to Grýla and her thirteen Yule Lads. The enormous cat roamed the countryside during Christmas, and in some stories only the smallest Yule Lad, Stúfur, was capable of controlling the unruly monster, riding it across the snow-covered landscape in search of prey.

Vargin

by

Tradition / Region: Belarusian mythology
Alternative names: Vargan
Category: Cat

The Myth

Vargin is an enormous demonic black cat regarded as the king of the feline kingdom. His fur is as black as coal, his eyes glow like flames, and his body is immense, with a pitch-black, furry tail as thick as a sable’s. He can appear and disappear without warning, squeeze through tiny cracks despite his size, and even pass through closed doors and windows. He is also able to assume the forms of butterflies, monstrous creatures, or humans, and is accompanied by evil spirits. His purring is said to lull people into a false sense of peace before bringing them misfortune.

Belarusian folklore tells that Vargin is one of the rulers of the animal world. The king of cats is Vargin, the king of roosters is Budzimir, and the king of mice is Podnor. While Budzimir represents peace and light, Vargin embodies torment, fear, and darkness.

Vargin is believed to prey upon people suffering from severe mental illnesses or emotional despair. Rather than causing ordinary physical sickness, he drives victims into confusion, social isolation, and complete mental and physical exhaustion. He especially torments those whose illnesses cannot be explained or cured, feeding upon their suffering.

One tale tells of a man named Tomas whose wife became mysteriously ill after insects entered her head. Doctors could not cure her. Tomas lovingly kept a black cat that everyone admired for its gentle nature, but a healer warned him that black cats, especially unknown ones, could bring terrible misfortune. The healer revealed that the beloved cat was actually Vargin, whose comforting purring concealed his true purpose of tormenting the household.

Another story tells of Budzimir being seized by Vargin, causing fear to spread throughout the world. An oak advised that Budzimir should be freed by calming and soothing Vargin rather than confronting him directly. Once the fire within the cat was allowed to fade and he became gentle, Budzimir was released and peace returned.

Despite his immense supernatural power, Vargin is said to fear only a powerful natural healer or sorcerer capable of driving him away with sacred words. Such healers can banish both Vargin and the evil spirits that accompany him.

Splintercat

by

Tradition / Region: American Mythology
Alternative names: None known
Category: Cat

The Myth

The Splintercat is a fierce nocturnal feline that flies through the air at tremendous speed. It is said to smash headfirst into large trees, knocking off their branches and leaving the trunks dead and stripped bare like pale ghostly snags. It performs this remarkable feat to expose raccoons and wild bees hiding inside the trees for food. Constantly battering trees with its head leaves the creature with a perpetual headache, making it notoriously ill-tempered and dangerous to approach.

An alternate tradition from Nova Scotia describes the Splintercat as emerging from trees during winter after spending the summer hibernating inside them. The loud cracking sounds heard in frozen forests are said to be the creature breaking free from its tree. In this version, it has exceptionally long claws, powerful legs, and fur patterned like tree bark, allowing it to remain perfectly camouflaged until it suddenly leaps from the shadows to ambush its prey.

Nunda

by

Tradition / Region: Tanzania Mythology, Kenya Mythology, Mozambique Mythology
Alternative names: Mla Watu (Eater of People)
Category: Cat

The Myth

The Nunda began as the unusually fierce cat of Sultan Majnún. As it fed on increasingly larger prey, it grew into a gigantic monster described as being larger than an elephant, with small ears, a broad body, two civet-like markings, and a thick tail.

The cat first killed a calf, but the Sultan dismissed the incident, insisting that both the cat and the calf belonged to him. As it continued killing and eating a goat, a cow, a donkey, a horse, a camel, a child, and finally a man, the Sultan still refused to punish it. Growing ever larger on its diet of flesh, the cat eventually left the city and hid in the surrounding wilderness, ambushing travelers and sneaking into the roads at night to carry away anyone it found. The population gradually dwindled while the Sultan ignored every warning.

Only after the monster attacked the Sultan himself and killed three of his sons did he realize the creature was no longer an ordinary cat. He sent his soldiers to destroy it, but the Nunda killed many of them and scattered the rest.

The Sultan’s youngest son then swore to avenge his brothers. Carrying only a spear and knife, he set out alone to hunt the beast. Mistaking many large animals for the monster, he successively killed a dog, civets, a zebra, a giraffe, a rhinoceros, an elephant, and several other creatures, proudly bringing each one home. Each time his mother told him it was not the Nunda and described the true monster’s appearance.

Eventually the prince and his companions found the Nunda asleep beneath a grove of trees. Recognizing it from his mother’s description, they fired their guns into the beast before retreating for the night. Returning the next morning, they found the gigantic monster dead. Its carcass was dragged back to the city in triumph, buried beneath the ground, and a house was built over its grave with a guard stationed there.

Other versions of the legend describe the Nunda as an insatiable monster capable of swallowing an entire population. In those tales, a lone hero kills the beast, cuts open its belly, and frees all of its victims alive.

Okazaki-ba-neko

by

Tradition / Region: Japanese Mythology
Alternative names: Okazaki Cat Monster, Spirit of the Maruko Cat Stone
Category: Cat

The Myth

The Okazaki-ba-neko first appears as an old woman wearing a twelve-layered kimono that had served as a burial shroud. She is accompanied by two pet cats that stand upright and dance, while she extends an unnaturally long tongue to lick oil from a lamp. Later she reveals her true form as a monstrous cat and finally transforms into a Kasha after emerging from the Cat Stone.

Osode traveled with her husband, Nakano Tosuke, and their infant child in search of her elder sister Omatsu, who had sold herself to earn money for their mother’s medicine. Unable to find a place to stay, they were led by their acquaintance Okura to an abandoned temple outside the post town.

Inside the temple, Osode encountered her mother, who was believed to have died of illness. The old woman was actually the monster cat in disguise. Okura witnessed the two pet cats standing on their hind legs and dancing while the old woman licked oil from a lamp with her long tongue. Because Okura had been born in the Year of the Rat, she was devoured by the cat.

At the same time, the ghost of Omatsu appeared before Osode and Fujisuke. It was revealed that Osode had unknowingly cursed her own sister, believing her to be a rival for Fujisuke’s affection. The curse disfigured Omatsu’s face, causing her to wander in search of a buyer before she was eventually murdered by Akahori Mizuemon. After learning the truth, Fujisuke declared he would divorce Osode. Overcome with despair, Osode died on the spot.

A monstrous hand then reached through a shoji screen, dragging away Osode’s body and her infant child. Behind the screen, the old cat-woman devoured them before revealing herself as the combined spirit of the Cat Stone and the ghost of Omatsu, after which she disappeared.

Later, as Omatsu’s body was brought for burial, a violent thunderstorm erupted. The Cat Stone opened its eyes and breathed fire before transforming once more into the old woman. She assumed the form of a monstrous Kasha, seized Omatsu’s corpse, and disappeared into the clouds.
