In 1888, a farmer near Beni Hasan in Middle Egypt dug into a pit and found tens of thousands of mummified cats. He had stumbled on one of the largest animal cemeteries in the ancient world. What happened next tells you everything about the distance between the civilization that made those mummies and the one that found them.
Nineteen and a half tons of cat mummies were loaded onto ships and sent to Liverpool. At auction, the auctioneer used a mummified cat skull as his hammer. The lot was sold to fertilizer companies, ground into powder, and spread across English fields.
The civilization that produced those mummies had spent seven hundred years wrapping cats in linen and painting their cases with care. They laid them in underground galleries as offerings to a goddess. The civilization that received them turned the whole shipment into plant food in an afternoon.
Both responses are human. Both are real. And the gap between them is where this story lives.
The Grain Deal
The cat chose us. That is not a metaphor.
Around 10,000 years ago, somewhere in the Fertile Crescent, the first farmers began storing grain. Grain attracted mice. Mice attracted the Near Eastern wildcat, Felis lybica lybica. The wildcats that tolerated human proximity ate better than those that didn’t. Over generations, the tolerant ones stayed. Humans noticed fewer mice. Nobody signed a contract. The arrangement worked.
A 2007 genetic study by Carlos Driscoll and colleagues, published in Science, confirmed that every domestic cat on Earth descends from this single wildcat population. Not the European wildcat, not the sand cat or the jungle cat. One subspecies, one region.
The oldest archaeological proof of this relationship sits on Cyprus. In 2004, French archaeologist Jean-Denis Vigne published a finding from Shillourokambos, a Neolithic village on the island’s southern coast: a cat buried forty centimeters from a human grave, in a parallel pit, with the same east-west orientation. The date was approximately 7500 BC.
Cyprus has no native wildcats. Someone carried that cat across the sea.
That burial predates the earliest Egyptian evidence by four thousand years. Egypt did not domesticate the cat first. The Fertile Crescent did. But Egypt did something with the cat that no other civilization attempted. Egypt made it a god.
And Egypt was not alone in recognizing something in this animal. In China, farmers worshipped Li Shou, a cat deity mentioned in the Book of Rites, one of the Five Classics of Confucianism. Li Shou protected grain from rats. Vikings brought cats aboard their longships to guard food stores of dried fish and grain. The Islamic world welcomed cats into homes and granaries and eventually into mosques.
Every grain-storing civilization on Earth discovered the same partner. And then, in culture after culture, something happened that went beyond gratitude for pest control.
Egypt: From Mouser to God
Bastet started as a killer.
In her earliest form, during the Second Dynasty (c. 2890-2686 BC), she was a lioness. Seal impressions from Saqqara show her name. The Pyramid Texts, carved into the walls of Fifth and Sixth Dynasty tombs around 2400 BC, reference her as a fierce protector associated with the “Eye of Ra,” the scorching, destructive force the sun god unleashed on his enemies.
She was, at this point, nearly identical to Sekhmet. Both were lioness-headed, both carried the ankh and the papyrus scepter. Both could destroy.
Then Egyptian theology split them apart. Sekhmet kept the destruction. Bastet absorbed the protection and the gentleness, the fertile side. The “Destruction of Mankind” myth describes Ra sending his Eye as a raging lioness to punish humanity, then pacifying her with beer dyed red to look like blood. The pacified form became Bastet. The raging form stayed Sekhmet.
By the New Kingdom (c. 1550-1069 BC), Bastet was increasingly shown with the head of a domestic cat rather than a lioness. The transformation was complete by the Twenty-Second Dynasty (c. 943-716 BC), when pharaohs from Bubastis, the city sacred to Bastet, took the throne and elevated her cult to national status. Shoshenq I made Bubastis a royal city. Osorkon II built a festival hall there that Edouard Naville would excavate in 1887-1889.
By the Late Period, Bastet was a seated cat holding a sistrum. The war goddess had become the purring protector of homes.
The Festival
Herodotus visited Egypt around 450-440 BC and described the annual festival of Bastet at Bubastis as the largest religious gathering in all of Egypt. He claimed seven hundred thousand people attended, a number that is almost certainly exaggerated. The scale was real even if the count wasn’t.
Pilgrims traveled by boat along the Nile and its Delta canals. Musicians played flutes and castanets. Women shook sistra, the sacred rattles of Hathor and Bastet. When the boats passed riverside towns, the women on board shouted insults at the women on shore and lifted their skirts. Herodotus records this without embarrassment. Ritual obscenity was standard in ancient Egyptian fertility festivals.
At Bubastis, the festival involved massive cattle sacrifices, music and dancing, and staggering amounts of wine. Herodotus claims more grape wine was consumed at this festival than during the entire rest of the year.
He called the temple “the most pleasing to the eye” in Egypt, though not the largest. It sat on a raised platform surrounded on three sides by tree-lined canals, each a hundred feet wide. A paved approach road four hundred feet wide led to the entrance.
This was no quiet shrine. This was ancient Egypt’s biggest party, thrown for a cat.
The Mummy Factory
The devotion had a dark underside. By the Late Period (664-332 BC), temples operated what amounted to cat breeding farms. They raised cats for the sole purpose of killing them and mummifying them, then selling the wrapped bodies to pilgrims as votive offerings to Bastet. The scale was industrial. Modern estimates suggest millions of cats were mummified over roughly seven hundred years.
In 2015, Lidija McKnight at the University of Manchester published results from CT scans of animal mummies across UK collections. Approximately one-third contained no animal remains at all. They were bundles of mud, sticks, and reeds wrapped to look like a mummified cat. Votive substitutes, made for pilgrims who couldn’t afford (or didn’t care about) the real thing.
The mummies that did contain cat remains told a harder story. Many showed broken necks and skull fractures consistent with blunt force trauma. Some contained kittens only a few months old. The cats were killed to order.
This is the tension at the heart of the Egyptian cat cult. The same civilization that mourned a cat’s natural death by shaving their eyebrows (Herodotus, Histories II.66) also ran factories that bred kittens and snapped their necks to meet consumer demand. Devotion and commerce lived in the same temple.
The Law, the Mob, and the Battle
Diodorus Siculus visited Egypt around 60-56 BC and wrote, in his Bibliotheca Historica (Book I, Chapter 83), that killing a cat in Egypt, intentional or not, was punished by death. He describes a Roman soldier who accidentally killed a cat and was torn apart by a mob despite the efforts of Egyptian officials and despite Egypt’s fear of Roman power. King Ptolemy himself could not save the man.
But look carefully at what Diodorus actually describes. This is mob justice, not written law. No pharaonic legal code prescribing death for cat-killing has ever been found. The reverence was real. The “death penalty” was a street verdict, not a statute.
Then there is the Battle of Pelusium. In 525 BC, the Persian king Cambyses II defeated Egypt’s Psamtik III in a battle at Pelusium, on the empire’s eastern frontier. The famous version of the story says Cambyses ordered his soldiers to carry cats and other sacred animals on their shields, or to drive them before the army. The Egyptians, unable to harm the sacred animals, refused to fight.
It is a fantastic story. It is almost certainly a legend. The source is Polyaenus, a 2nd-century AD author writing six hundred and fifty years after the battle. Herodotus, who visited the actual battlefield within living memory of the event and wrote extensively about it (Histories III.1-13), mentions nothing about cats. If the story were widely known in Egypt, Herodotus would have included it. He included everything.
The battle happened. The cat detail is a later invention. But the fact that someone invented it, and that it has been repeated for two thousand years, tells you something about how deeply the Egyptian-cat association lodged in the human imagination.
1233: The Year of the Cat
In June 1233, Pope Gregory IX issued a papal bull called Vox in Rama (“A Voice in Ramah”). It was addressed to King Henry VII of Germany, the Archbishop of Mainz, and a papal inquisitor named Konrad von Marburg. Konrad had reported that Luciferian heretics in the Rhineland were conducting diabolical rites.
The bull describes the initiation ritual of the alleged sect. A toad appears. A pale, cold man appears. And then a black cat, “the size of a moderate dog,” descends backward on a rope. The initiates kiss the cat’s rear. The devil appears in the form of a half-man, half-cat. The ceremony proceeds from there.
This is the document that popular history credits with starting a centuries-long war on cats. “The Pope declared cats were agents of the devil.” “Medieval Europe killed its cats and got the plague.” You will find these claims in a hundred articles online.
What the document actually says is more limited. Vox in Rama describes a black cat appearing in one specific heretical ritual, based on the testimony Konrad von Marburg extracted through his inquisition. The bull does not associate the ritual cat with real domestic cats. It does not declare cats incarnations of Satan. It does not order anyone to kill a cat. Konrad von Marburg himself was murdered by a mob in July 1233, weeks after the bull was issued. His inquisition was hated.
Now hold that date. 1233.
In the same year, on the other side of the world, a Japanese court noble named Fujiwara no Teika made an entry in his diary, the Meigetsuki (“Chronicle of the Bright Moon”). He recorded the nekomata: a supernatural cat, a creature that transforms, a being with a forked tail and powers beyond the animal world.
This is the first written appearance of the supernatural cat in Japanese literature. 1233. The same year a papal bull in Germany placed a black cat at the center of a devil-worshipping ritual.
Two civilizations with zero contact. No trade routes between medieval Germany and Kamakura-era Japan. No shared literary tradition, no common mythology, no way for one to influence the other.
Both, in the same year, put in writing the same fear: this animal is not entirely what it appears to be.
The Devil’s Cat
The association between cats and witchcraft grew slowly after Vox in Rama, but it did grow.
By the fourteenth and fifteenth centuries, black cats had become linked to witchcraft across parts of Europe, particularly in regions where inquisitions were active. The connection was strongest in England and Scotland, where the concept of the “familiar” took hold. A familiar was a spirit, often in animal form, that served a witch. And the most common familiar, in English trial records, was the cat.
The Chelmsford witch trials of 1566, among the earliest major witch trials in England, featured testimony about a white-spotted cat named Sathan that was allegedly passed between women and fed blood. The Pendle witch trials of 1612 included similar testimony about cat familiars. The Malleus Maleficarum (1486) mentions witches transforming into cats, though the text spends more time on other matters.
On the continent, cats suffered in more direct ways. In Metz, France, cats were burned alive in baskets on the Eve of the Feast of St. John (June 23), a practice documented from the medieval period through at least the seventeenth century. In Ypres, Belgium, cats were thrown from the belfry of the Cloth Hall during an annual festival. The last real cat was thrown in 1817. The festival continues as a triennial event (since 1938) using toy cats.
Robert Darnton’s The Great Cat Massacre (1984) analyzes an episode from the 1730s in which printing apprentices on the Rue Saint-Severin in Paris killed their master’s cats in a mock trial. Darnton reads this as symbolic class warfare. The cats belonged to the master’s wife, who lavished care on them while the apprentices starved. Killing the cats was a coded attack on the master’s household. The workers thought it was the funniest thing that had ever happened.
The Plague Myth
You will often read that medieval Europeans killed so many cats, because of their association with witchcraft, that rat populations exploded and enabled the Black Death of 1347-1353.
This is almost certainly wrong.
The Black Death was caused by Yersinia pestis, transmitted primarily by fleas on rats and by human-to-human pneumonic infection. The cat killings, while real in specific regions and periods, were never continent-wide. They were concentrated in areas with active inquisitions or specific local traditions. Most of medieval Europe kept its cats. The scale of cat killing was nowhere near sufficient to affect rat populations across an entire continent.
Snopes investigated this claim in 2023 and found no solid historical evidence connecting cat persecution to plague severity. The narrative is clean and satisfying. It is also an oversimplification of both the cat persecution (regional, not universal) and plague transmission (which does not depend on cat-to-rat predation ratios at a continental scale).
Black Cats: The Great Divergence
The black cat superstition split is one of the strangest things in all of folklore.
In Britain, a black cat crossing your path is good luck. In Scotland, a strange black cat arriving at your home signals prosperity. In Wales, a black cat means good health. In Japan, black cats were traditionally considered fortunate.
In America, a black cat crossing your path means bad luck. On the European continent, black cats are associated with witchcraft and misfortune.
The split has a history.
England never experienced large-scale cat persecutions comparable to parts of the continent. English folk magic saw cats as useful and sometimes protective, even when the familiar tradition existed alongside it. The older Celtic associations, where cats were powerful and dangerous but also generous if treated with respect, survived.
The Puritans who settled America came from the most witch-obsessed strain of English Protestantism. They carried continental European fears of black cats to the New World, where the association with witchcraft hardened into permanent superstition. The same cultural current that produced the Salem trials of 1692 also produced America’s black cat phobia.
Britain kept the older belief. America inherited the newer fear. The Atlantic Ocean became the dividing line between good luck and bad.
The Prophet’s Cat
The Islamic world took a different path with cats entirely.
The most famous story is about Muezza, the Prophet Muhammad’s favorite cat. According to the tale, Muezza fell asleep on the sleeve of Muhammad’s robe. Rather than disturb the sleeping cat, Muhammad cut off his sleeve and went to prayer. When he returned, Muezza bowed in thanks, and Muhammad stroked her three times. From that moment, cats could always land on their feet.
It is a beautiful story. It has no basis in canonical hadith. It does not appear in Bukhari, Muslim, or any of the six major hadith collections. The earliest attributions trace to much later sources, possibly the 12th-century Sufi founder Shaykh Ahmad al-Rifa’i or later compilations. The Muezza story is beloved tradition, passed down through centuries of Islamic culture. It is not a historically verified account of the Prophet’s life.
What is verified tells a more grounded story.
Abu Hurairah, one of the most prolific narrators of hadith in Sunni Islam, bore a name that means “Father of the Kitten.” Early biographical sources confirm the nickname came from his affection for cats. He reportedly carried a kitten in his sleeve.
Sahih al-Bukhari (2365 and 3318) records a hadith about a woman who imprisoned a cat, refused to feed it or let it hunt, and was punished for it in the afterlife. This is one of the most frequently cited hadiths about animal cruelty, and the animal at its center is a cat.
The hadith that shaped Islamic law most directly comes through Kabsha bint Ka’b, recorded in Sunan Abu Dawud and Malik’s Muwatta. A cat drank from a vessel of water. Abu Qatadah, Kabsha’s father-in-law, tilted the vessel so the cat could drink more easily, and explained that the Prophet had said cats are “not impure; they are among those who go around among you” (at-tawwafin). The Arabic carries a domestic warmth: cats are part of the household, part of the daily coming and going.
This hadith established cats as ritually clean (tahir) in Islamic jurisprudence. Their saliva does not make water impure. They can roam freely in mosques. They are considered domestic animals deserving of care.
The contrast with medieval Christian Europe is stark. In the same centuries that parts of Europe burned cats in baskets and threw them from bell towers, the Islamic world let them sleep on prayer rugs. Two religions of the same Abrahamic root, opposite conclusions about the same animal.
Istanbul’s mosque cats are the living continuation of this tradition. Cats in their proper place.
Shape-Shifters: Japan and the Celtic Isles
The Forked Tail
The nekomata that Fujiwara no Teika recorded in 1233 was only the beginning. Over the following centuries, Japanese folklore developed a rich and terrifying catalog of supernatural cats.
The nekomata (“forked cat”) was a cat whose tail split in two after reaching great age or size. In early accounts it was a mountain-dwelling monster. Later traditions merged it with the bakeneko (“changed cat”), a domestic cat that transformed after living long enough. The bakeneko could walk on its hind legs and speak human language. It could shapeshift into the form of its dead owner or other humans.
The Nabeshima Bakeneko Disturbance is the most famous cat ghost story in Japanese literature. A retainer of the Nabeshima clan in the Saga Domain is killed by his lord. The retainer’s mother tells her grief to the family cat and then takes her own life. The cat, soaked in her blood, becomes a bakeneko and torments the lord Nabeshima Mitsushige night after night until a loyal retainer destroys it. The story became a staple of kabuki theater and ukiyo-e prints. In the Edo period (1603-1868), bakeneko stories flourished. Some involved cats transforming into beautiful women in the pleasure quarters. Others featured vengeful cats haunting families who had mistreated them.
The fear was specific enough to shape behavior. Many Japanese households cut their cats’ tails short to prevent them from splitting and the cat from gaining supernatural powers. This practice may be the origin of the Japanese bobtail breed.
The maneki-neko, the “beckoning cat,” offers the friendly counterpart. The earliest documented reference appears in 1852, in the Buko nenpyo (“Chronology of Edo”). The origin temple is disputed. Gotoku-ji in Setagaya claims a cat beckoned the feudal lord Ii Naotaka inside the temple moments before lightning struck where he had been standing. Imado Shrine in Asakusa makes its own claim. The raised right paw beckons money. The raised left paw beckons customers. By the Meiji period (1868-1912), the maneki-neko was everywhere.
Japan’s relationship with cats contained both extremes at once. The same culture produced the monstrous nekomata and the lucky maneki-neko. Fear and fortune, in the same animal.
The Fairy Cat
Scottish and Irish Gaelic folklore has the Cat Sith (Cat Sidhe): a fairy creature the size of a dog, black all over except for a white spot on its chest. It walks on all fours when humans watch. When no one is looking, it walks on its hind legs.
There were two theories about the Cat Sith’s nature, even within the folklore itself. Some said it was a fairy, a being from the Otherworld. Others said it was a witch who had transformed into a cat. A witch could make this transformation nine times. On the ninth, she remained a cat forever.
Nine transformations. Nine lives. The connection has never been proven, but it sits there.
The Cat Sith’s most feared power was stealing souls. If a Cat Sith passed over a dead body before burial, it could take the soul before it reached the afterlife. This belief produced the Feill Fhadalach, the Late Wake: a vigil held over the dead body until burial. Watchers played music, told riddles, wrestled, and scattered catnip to distract any Cat Sith that might approach. No fire was lit in the room with the body, because cats were thought to be drawn to warmth.
On Samhain (the origin of Halloween), households left a saucer of milk outside for the Cat Sith. If you left the milk, your cows would produce well for the year. If you didn’t, the Cat Sith would curse your cows and dry up their milk.
The Cat Sith likely has a real-world basis. The Kellas cat, a hybrid between domestic cats and Scottish wildcats, is a large, black, muscular animal found in the Scottish Highlands. The first specimen was scientifically documented in 1984, shot near the village of Kellas in Moray. A specimen sits in the National Museum of Scotland in Edinburgh. It looks exactly like what the folklore describes: a black cat the size of a small dog.
The Christmas Cat
Iceland has its own entry in the supernatural cat catalog. The Jolakotturinn, the Yule Cat, is a massive feline that roams the countryside during the Christmas season and eats anyone who has not received new clothes before Christmas Eve.
The first written mention comes from Jon Arnason’s 1862 collection of Icelandic folktales. The poet Johannes ur Kotlum popularized the figure in 1932 with a poem called “Jolakotturinn” in his collection Jolin koma (“Christmas Is Coming”). By the mid-twentieth century, the Yule Cat had been adopted into the family of Gryla, the ogress mother of Iceland’s thirteen Yule Lads. The cat became her pet.
The social function was practical. Wool processing had to be finished before Christmas. Workers who completed their share received new clothes. Those who didn’t had nothing new to wear. And the Yule Cat was waiting.
Folklorist Arni Bjornsson suggests the entire creature may stem from a figure of speech, “to dress the cat,” that was taken literally. Archaeologist Gudmundur Olafsson connects it to continental European St. Nicholas companion figures who punished the naughty. Either way, Iceland produced the only Christmas tradition where the threat is a giant cat that eats you for being lazy.
Freyja’s Chariot and the Viking Pelts
Norse mythology gives cats their highest transport assignment. In the Prose Edda, Snorri Sturluson writes in Gylfaginning (chapter 24) that the goddess Freyja drives a chariot pulled by cats. In chapter 49, she arrives at Baldr’s funeral in this chariot.
The cats are not named in any medieval source. The names “Bygul” and “Trjegul” that circulate online come from American author Diana Paxson, a modern invention presented as authentic. The medieval texts give no names.
What kind of cats pulled the chariot of a goddess? The popular answer is the Norwegian Forest Cat (Skogkatt), a large, long-haired breed native to Scandinavia. Others have proposed boreal lynxes. A third theory traces the image to Cybele, the Anatolian mother goddess whose chariot was drawn by lions. As the iconography traveled north and west through Roman trade routes, the lions may have become large cats, fitting the available fauna. Freyja absorbed several of Cybele’s attributes: fertility, sexuality, a connection to wild nature. The chariot cats may have traveled the same route.
Freyja herself ruled over love, fertility, war, and death. She received half the battle-slain in her hall Folkvangr. The cat association fits her domestic and fertile aspect, the same duality that Bastet embodied in Egypt: a goddess of both comfort and power.
The archaeological record tells a less romantic story. At the Viking fortress of Nonnebakken in Odense, Denmark, archaeologists found the remains of sixty-eight cats in a well. Cut marks on the bones and broken necks showed they had been skinned. Between 850 and 1050 CE, cat pelts became a valuable trade commodity in Denmark. The Eirik the Red Saga mentions catskin gloves worn by a volva (seeress) during a ritual. The garment choice may connect to Freyja’s cat association, the seeress dressed in the skin of her goddess’s sacred animal.
Vikings also brought cats aboard ships. Genetic evidence shows that cats first appeared at Scandinavian urban settlements, not rural farms. They arrived from overseas. From the ports, cats spread to the countryside. A 2018 study reported in Science found that domesticated cats grew approximately sixteen percent larger between the Viking Age and today.
The Vikings worshipped a cat goddess and skinned cats for their fur. They carried cats on their ships to protect their food. Reverence and utility lived side by side, just as they had in Egypt.
The Rain Cat and the Choosing Cat
Thailand
In the Isan region of northeastern Thailand, there is a rain-calling ceremony called Hae Nang Maew, “the parading of a female cat.”
The ritual starts with selecting a Si Sawat cat, the breed Westerners know as the Korat. Cloud-colored or black cats are preferred. The cat is placed in a bamboo or rattan basket with a cover and carried through the village in a procession. Villagers sing, dance, and splash water onto the basket as it passes.
The logic is this: cats hate water. When a cat gets wet, it cries. The cat’s cry is a plea to the clouds to break and release rain.
“Si Sawat” means greyish-blue. The word “sawat” alone means prosperity, or good luck. The Korat is still called “the good luck cat of Thailand.”
Thailand’s relationship with cats produced one of the strangest documents in feline history: the Tamra Maew, the “Cat-Book Poems.” These manuscripts, believed to originate from the Ayutthaya period (1351-1767), are concertina-folded books made from mulberry bark. They contain painted illustrations of cat breeds with accompanying descriptions in Thai poetic verse.
The manuscripts list seventeen auspicious cat breeds. They also warn against unlucky cats: tiger-patterned coats, cats with blood-red eyes, cats that ate their own young. The manuscripts survive in the National Library of Thailand, the British Library, the National Library of Australia, and the Library of Congress. A kingdom that classified cats by their fortune-bearing properties and preserved those classifications in hand-painted manuscripts on mulberry bark.
China
Chinese mythology tells a story about cats that no other culture tells.
When the gods created the world, they put cats in charge. Li Shou was the leader of the cats. The gods checked in periodically and found the cats napping in sunbeams and chasing butterflies. Administrative duties went untouched. Three times the gods came. Three times the cats were asleep.
Li Shou spoke to the gods. Humans, she said, seemed more interested in running things. Cats would prefer to simply enjoy the world. The gods agreed. They transferred the power of speech from cats to humans, and humans took over the management of creation.
Cats lost the ability to speak. They gained the freedom to do as they pleased.
The Book of Rites (Liji), one of the Five Classics of Confucianism, describes a year-end harvest ritual where cats received offerings because they devoured the rats and mice that damaged crops. Farmers honored cats for protecting the grain. The creation myth, with its talking cats and voluntary retirement, comes from a separate Chinese folk tradition whose original text is unclear. But the reverence is the same in both. The Chinese word for cat, mao (猫), is a near-homophone of mao (耄), meaning old age. Cats became symbols of long life.
The Chinese creation myth is unique. In every other culture, cats either earned divine status through service (Egypt, China’s Li Shou at the practical level) or acquired supernatural fear through their behavior (Japan, Celtic lands, medieval Europe). Only in China did the cats choose to step down. They looked at the burden of running the world and said: no, thank you.
The Parasite in the Room
There is one more thread, and it is the strangest.
Toxoplasma gondii is a single-celled parasite that can infect virtually any warm-blooded animal. But it can only complete its sexual reproductive cycle in the intestines of cats. Cats are its definitive host. Every other animal, including humans, is an intermediate host, a way station.
The parasite is startlingly common. Estimates suggest thirty to fifty percent of the world’s human population carries a latent Toxoplasma infection, with rates varying dramatically by region. In some parts of France and Brazil, infection rates exceed eighty percent.
Jaroslav Flegr, an evolutionary biologist at Charles University in Prague, has spent decades studying the behavioral effects of Toxoplasma in humans. His research, published across numerous peer-reviewed journals, suggests that infected individuals show slower reaction times, higher rates of traffic accidents, and changes in personality profiles that correlate with increased risk-taking and decreased fear of novelty.
In 2018, Stefanie Johnson and colleagues published a study in Proceedings of the Royal Society B that found Toxoplasma-positive individuals were 1.8 times more likely to have started their own business. The parasite that can only reproduce in cats appeared to make its human hosts more entrepreneurial.
The mechanism is understood in rodents. Toxoplasma infection in rats reduces their fear of cat urine. Infected rats approach cats more readily and get eaten. The parasite completes its life cycle. In humans, the behavioral changes are subtler. The connection between infection and risk-taking is correlational, not definitively causal. The research is ongoing.
The research leaves a question open.
Ancient civilizations that lived in close contact with cats had higher exposure to Toxoplasma. Egypt, where cats lived in homes, slept in beds, and were bred by the millions in temple complexes. The Islamic world, where cats roamed freely through houses and mosques. Any grain-storing civilization where cats and humans shared close quarters for generations.
If Toxoplasma infection alters human behavior toward risk-taking and reduced fear, and if populations with dense cat contact had higher infection rates, the parasite may have played a role in the cultural relationship between humans and cats. The civilizations that worshipped cats may have done so, in part, because a cat-borne parasite was altering their collective behavior.
We do not know. Flegr’s work is respected but controversial. The leap from individual behavioral correlations to civilizational-scale cultural effects is enormous and unproven. No study has attempted it.
But the question exists. The parasite exists. The behavioral effects exist. And the pattern, the cross-cultural, cross-continental, cross-millennial veneration of a single domestic animal, exists. Whether these things are connected is unknown. That they coexist is a fact.
The Animal That Sees
Ten civilizations. Three continents. At least three thousand years of continuous record. They all arrived at the same place.
The dog did not produce this pattern. The horse did not. Cattle, goats, sheep, chickens: none of them. Humans kept all of those animals for far longer than they kept cats. None generated the same combination of worship and fear, transformation myths and soul-stealing, divine status and devil-association, all attached to one species, by cultures that had no contact with each other.
The materialist reading is straightforward. Cats were useful pest controllers. Cultures that stored grain valued them. The religious veneration was social expression of economic utility. The supernatural associations, transformation, soul-stealing, devil worship, are projections of the cat’s nocturnal, independent nature onto cultural anxieties about things that cannot be controlled. The eyes that shine in the dark, the silent appearance and disappearance, the refusal to obey: all of it mapped onto existing fears about the boundary between the tame and the wild, the known and the unknown. Everything reduces to mice in the granary and human pattern-recognition.
The other reading is this.
The pattern is too consistent and too specific. Dogs are useful. Horses are useful. Goats and cattle and chickens are useful. None of them triggered worship in Egypt and China at the same time. None of them generated transformation myths in Japan and Scotland at the same time. And none were placed at the center of devil-worship accusations in Europe while being recorded as supernatural beings in a Japanese court diary, in the same calendar year, by civilizations that could not possibly have influenced each other.
Something about the cat triggered a response in the human mind that no other domesticated animal triggered. The independence and the nocturnal vision. The way a cat watches things that are not there, or are not there for human eyes. The purr, a vibration with no definitively established biological purpose. The pupils that shift from slits to black circles. The ability to appear from nowhere and vanish without sound.
Ancient people across ten cultures noticed the same thing in this animal. They had different names for it. Different stories. Different levels of reverence and fear. But the recognition was the same: this creature operates on a frequency we do not fully share.
Whether they were right is an open question.
That they all noticed it is not.
