The History of Black Cat Superstitions: From Egyptian Goddesses to Halloween Mascots

Black cat superstitions did not start with witches. They started with a Greek myth, a misunderstood Egyptian goddess, a medieval pope, and roughly 800 years of bad PR. Cross the path of a black cat in Rome and you have just been cursed, but cross the same path in Edinburgh and you are about to come into money. The exact same animal, the exact same crossing, two opposite predictions. The story of how that split happened is messier and funnier than the Halloween version, and it runs from pharaoh tombs to a 1233 papal bull to a 2025 shelter report on adoption rates. Let us untangle it.

Origins in Ancient Egypt: Bastet and the Sacred Cat

The earliest organized cat reverence on record belongs to Egypt, around 3000 BCE. The goddess Bastet was depicted with a cat head and a lithe human body, and her cult center at Bubastis pulled in pilgrims by the boatload. Herodotus, who visited in the 5th century BCE, claimed the annual festival drew 700,000 people. Cats of every color were sacred, but the dark coated ones held a particular place because they resembled Bastet in her nocturnal protector aspect.

Killing a cat in Egypt, even by accident, could earn a death sentence. Diodorus Siculus recorded the case of a Roman traveler lynched in Alexandria for killing one before Pharaoh Ptolemy could intervene. Cats were mummified by the hundreds of thousands. A single dig at Beni Hasan in the 1880s produced about 80,000 cat mummies, which a British firm bought at auction for four pounds per ton and ground up for fertilizer.

At this point in history, a black cat was not unlucky. It was, depending on the temple, a small ambulatory god.

The Greek and Roman Pivot: Hecate and the First Bad Omen

The Greeks borrowed Bastet but reshaped her into Hecate, goddess of crossroads, magic, and the dark moon. Hecate kept a black cat as a familiar in some traditions, which is the first time we see the specific pairing of black cat plus female magical practitioner that medieval Europe would later weaponize.

The Romans, who borrowed almost everything from the Greeks, kept the cat goddess connection but added a new wrinkle: the haruspex tradition of reading omens from animal behavior. A black cat crossing a soldier’s path was already considered unlucky by the early Empire, although Roman writers also recorded the cat as a household guardian. Cats are recurring puzzles in human thought, and they have been since at least 200 BCE. For more on how humans have struggled to categorize unusual animals across history, our piece on the Gulf of Alaska golden orb mystery covers a recent example of the same instinct.

The Roman Black Cat Tax Myth

One repeated claim is that the Romans imposed a tax on black cats specifically. There is no evidence for this in surviving records, but the legend persists. What is documented is that the Roman military took cats on campaign as rodent control, many of them black short-haired animals descended from the Egyptian temple population.

Medieval Europe: How a Papal Bull Made Black Cats Demonic

The decisive moment in black cat superstition history is dated, signed, and sealed. On 13 June 1233, Pope Gregory IX issued a papal bull called Vox in Rama. The document was a warning to the Archbishop of Mainz about an alleged Luciferian cult in Germany, and it described in lurid detail the initiation rites of the heretics. According to the bull, the new member kissed a large black cat under its tail, after which the cat would speak Latin and Lucifer would appear in the room.

Vox in Rama is the first official Church document to specifically link black cats to Satan. Historians like Donald Engels, in his 1999 book Classical Cats, argue that this single bull set off a chain of cat persecution across Catholic Europe that lasted roughly four hundred years. The bull was reissued and copied across dioceses, and parish priests cited it during sermons whenever cats needed to be blamed for crop failures, miscarriages, or strange noises in the rafters.

The downstream effects were quite literal. Cat populations in Central and Western Europe dropped sharply between 1250 and 1400. Rats, with fewer predators, expanded. Some historians, including Engels, have proposed that the resulting rat population boom helped the Black Death of 1347 spread more efficiently. The mechanism is debated, because Yersinia pestis is primarily carried by fleas on multiple rodent species, but the timing is suggestive enough that it shows up in nearly every popular history of the plague.

Witch Trials, Familiars, and the Burning of the Cats

The European witch trials, peaking between 1450 and 1700, gave black cat superstitions their final shape. The concept of a familiar, a demonic spirit in animal form that served a witch, was codified in the 1486 manual Malleus Maleficarum. Cats, particularly black ones, were the most commonly cited familiar in trial records. The 1566 trial of Agnes Waterhouse in Chelmsford, England, the first English witch trial to result in execution, featured a cat named Satan that allegedly murdered her neighbor on command.

Cats were burned alongside accused witches in some jurisdictions. The Metz cat festival in France, which ran from 1344 to 1773, involved publicly burning thirteen cats in iron cages every June 23rd to mark the feast of Saint John. Louis XIV personally lit the bonfire at one such festival in 1648 as a teenager, then later in life ordered the practice ended. The Metz festival was not unique. Similar cat burnings happened in Belgium, Denmark, and parts of Germany well into the 18th century.

The accumulated effect of four centuries of being burned, drowned, and walled into building foundations as protective charms is that the European cat genome bottlenecked. Modern genetic studies of European cat populations show reduced diversity in lineages that were heavily persecuted, although the bottleneck was not severe enough to threaten the species.

The Great Regional Split: Lucky in the UK, Unlucky in Italy

Here is where black cat superstitions get strange. Despite the shared medieval origin, post-Reformation Europe split sharply on whether the animals were good news or bad news, and the split tracks roughly with religious denomination and maritime tradition.

Lucky Territories

• United Kingdom: A black cat crossing your path is good luck. A black cat entering your home is excellent luck. Sailors’ wives kept black cats specifically to ensure their husbands returned safely.
• Scotland: A strange black cat appearing on your porch portends prosperity. The proverb runs: “Whenever the cat of the house is black, the lasses of lovers will have no lack.”
• Japan: Black cats bring good luck, particularly to single women seeking suitors. The famous maneki-neko beckoning cat is most often white, but the black variant is sold specifically as a ward against stalkers and evil spirits.
• Germany (Northern): A black cat crossing right to left is lucky. Left to right is unlucky. The direction matters.

Unlucky Territories

• Italy: A black cat crossing your path means you should turn around, take a different route, and possibly check your will. Italian folklore is the strictest in Europe on this point.
• Spain: Similar to Italy, with the additional belief that a black cat visiting a sick person hastens death.
• United States: A black cat crossing your path is unlucky. This came over with English settlers, but the English settlers in question were Puritans who had inverted the older English tradition during the witch trial era.
• India: A black cat crossing your path is widely considered a bad omen, and many people will wait for someone else to cross first or take a different route entirely.

The pattern that emerges is that Protestant maritime cultures rehabilitated the black cat once the witch trials faded, often because of the practical value of cats on ships. Catholic and Hindu cultures, with longer continuous traditions of associating cats with magical practitioners, kept the bad luck reading.

Sailors, Pirates, and the Black Cat at Sea

Maritime tradition is the single biggest reason the UK rehabilitated the black cat. From at least the 1600s, English and Irish sailors considered black cats essential good luck on a voyage. They kept the ship rat free, they were said to predict storms by becoming restless, and they were thought to attract favorable winds.

The Royal Navy from the Napoleonic era through World War I commonly listed a black cat as ship’s company, with a small daily ration. The sailor’s wife superstition was the logical extension. If a black cat at sea protected the ship, a black cat at home guided the sailor back. This belief was strong enough in coastal Yorkshire that the Whitby fish market records show a 30 percent price premium for black kittens in the 1880s.

Pirates, contrary to popular fiction, were not particularly superstitious about black cats. Surviving Caribbean pirate logs from the 1700s mention cats only as rat catchers, with no color preference. The black cat pirate aesthetic is largely a 20th century Hollywood invention.

How Black Cats Became Halloween Mascots in 20th Century America

The Halloween black cat is surprisingly recent. Halloween itself, descended from the Celtic festival Samhain, was brought to North America by Irish and Scottish immigrants during the 1840s famine waves. The early American Halloween involved bonfires, divination games, and apple bobbing, but black cats were not central to the imagery.

The shift happened between 1900 and 1930, driven primarily by the postcard industry. The Edwardian craze for collectible holiday postcards produced thousands of Halloween designs, and the visual shorthand of witch plus black cat plus jack-o-lantern became fixed in print. The 1902 Brundage postcards, the 1909 Whitney series, and the 1915 Tuck publications all leaned heavily on the black cat motif. By the time mass produced Halloween decorations became a thing in the 1930s, the association was locked in. Our coverage of the Backrooms internet mythology covers a similar process of fixed imagery emerging from a specific visual moment.

Hollywood added the final layer. Edgar Allan Poe’s 1843 short story The Black Cat had already established the literary template, but the 1934 Universal Pictures film The Black Cat, starring Boris Karloff and Bela Lugosi, codified the cinema version. The actual cat in the film has limited screen time, but the title and the promotional posters were enough to permanently cement the connection between black cats, horror, and October.

Modern Shelters and the Adoption Gap

Centuries of bad PR produced a measurable modern problem. American animal shelters have reported a black cat adoption gap since at least the 1980s, with black cats consistently waiting longer for homes than cats of other colors. The ASPCA confirmed in a 2015 internal study that black cats accounted for roughly 33 percent of intake but only 18 percent of adoptions in a one year sample across 14 partner shelters.

The reasons are debated. Some shelter directors blame the superstition itself. Others point to photography, arguing that black cats are harder to photograph for adoption listings because their facial features get lost in low light. The viral hashtag #BlackCatPhotoChallenge, which trended in 2019 and again in 2023, was a direct response. Shelter staff started teaching themselves and adopters how to light black cats properly, using a 45 degree key light with a slight rim light to bring out the eye color and whisker detail.

Some shelters refuse to adopt out black cats during the two weeks before Halloween, citing concerns about ritual abuse. Documented cases of actual Halloween black cat abuse are rare, and several large shelter networks have abandoned the policy because the suspension reduces overall black cat adoption rates and the underlying risk appears overstated.

FAQ

Are black cats actually unlucky?

No. The bad luck association is a medieval European cultural construct, and the inverse good luck association from the UK and Japan is equally arbitrary. The cat does not know what color it is and does not have opinions about your finances.

Why are black cats associated with witches?

The link is traceable to Pope Gregory IX’s 1233 papal bull Vox in Rama, which named black cats as participants in Luciferian rites. The witch hunting manuals of the 15th and 16th centuries reinforced the association, and four centuries of trial records cemented it in folk memory.

Is it true that black cats were killed during the Black Death?

Cat populations did decline sharply in Catholic Europe between 1250 and 1400 due to religious persecution, and this likely allowed rat populations to grow. The exact contribution to the spread of Yersinia pestis is debated, because the disease is carried by multiple rodent species and their fleas, but the timing is consistent.

Why are black cats good luck in the UK but bad luck in the US?

The US tradition was carried over by Puritan settlers in the 1600s, who held the older European bad luck view. The UK tradition flipped during the maritime expansion of the 17th and 18th centuries, when sailors and their wives heavily reinvested in the protective cat tradition. The settlers left before the flip happened.

Do black cats really wait longer in shelters?

Yes, although the gap has narrowed since the late 2010s as awareness campaigns and improved adoption photography have helped. Black cats still tend to spend more days in shelter than equivalent cats of other colors in most North American sample sets.

Conclusion

Black cat superstitions are a fossil record of European religious history compressed into one animal. Egypt sanctified them, Greece magicked them, Rome distrusted them, Gregory IX demonized them, the witch trials nearly exterminated them, sailors rehabilitated them, and Edwardian postcard printers turned them into October decorations. The result is a global folklore that contradicts itself across borders and survives mostly because cats keep showing up at our doors and we keep deciding what they mean. The cats are unimpressed.
