Around 60 BC, a member of a Roman delegation in Egypt killed a cat. Probably by accident. A crowd found his house, and neither the officials the king sent to beg for his life nor the general terror of Rome saved him. The Greek historian Diodorus Siculus wrote the scene down and added that he had watched it happen. That one paragraph has shaped how we picture cats in ancient Egypt more than every painted tomb wall combined, and it is also the most misquoted piece of evidence in the whole story.
The real history is stranger than the meme version. Egypt did not invent the domestic cat, the famous death penalty is not a surviving Egyptian law, and the millions of mummified cats in the desert were not beloved pets. Most were kittens, killed young, sold at temple gates.

Cats in Ancient Egypt Did Not Come First
In 2004, a French team led by Jean-Denis Vigne published a find from Shillourokambos, a Neolithic site in southern Cyprus, in the journal Science. In a grave roughly 9,500 years old, an eight-month-old cat lay about 40 centimetres from a human burial, at the same depth, in the same sediment, skeleton still articulated. Somebody put it there on purpose.
The detail that matters: cats are not native to Cyprus. Whoever brought that animal to the island loaded it onto a boat and crossed open water with it, thousands of years before anyone in the Nile Delta carved a cat into a temple wall. Egypt gets the credit because Egypt left the best pictures, not because Egypt went first.
Bastet Was a Lioness Before She Was a Cat
The goddess now sold on a million fridge magnets as a slim bronze housecat did not start out that way. Bastet appears in the earliest material as a lioness, a protector of the king with a temper, closer in function to her lion-headed counterpart Sekhmet than to anything that sits on a windowsill. The shift toward the domestic cat form happens gradually across the second millennium BC, until the feline version becomes standard. The softening of the goddess tracks the softening of the animal.
Per-Bast, the City Built for a Cat Goddess
Her cult city was Per-Bast, “House of Bastet”, which the Greeks turned into Bubastis. The site is Tell Basta, southeast of modern Zagazig in the eastern Nile Delta, identified during Napoleon’s 1798 expedition by Étienne-Louis Malus and excavated from 1887 by the Swiss Egyptologist Édouard Naville, who dated the main temple structure to Osorkon II in the ninth century BC. Bubastis was a royal seat under the 22nd Dynasty, and the cat goddess got the architectural budget that comes with being the home team deity of whoever is running the country.
What Herodotus Saw at the Festival
Herodotus visited in the fifth century BC and left a description in Book II of the Histories that reads like a travel writer who cannot quite believe his own notes. The temple, he says, is “very well worthy of mention, for though there are other temples which are larger and built with more cost, none more than this is a pleasure to the eyes.” Two channels ran in from the Nile, each about a hundred feet wide and shaded with trees, wrapping the building so completely that only the entrance stayed dry. The city around it had been banked up over centuries, so worshippers looked down into the sanctuary from every side.
The annual festival was not a quiet affair. Pilgrims arrived by boat, women shaking rattles, men playing flutes, everyone singing and clapping, stopping at each riverside town so the women could shout mockery at the local women and lift their skirts at them. At Bubastis, Herodotus writes, “more wine of grapes is consumed upon that festival than during the whole of the rest of the year.” Attendance ran to “seventy myriads of men and women, besides children”, which is 700,000, reported by a Greek tourist quoting locals, so treat it as a mood rather than a census. For a sense of how strange ancient ritual could get, the Roman well in Frankfurt with a skeleton and a bronze goddess at the bottom is a useful companion piece.
The Law That Made Killing a Cat a Capital Crime
Here is the careful version, because this is where the internet goes feral. No Egyptian legal text survives that says “kill a cat, die”. What survives is Greek testimony about Egyptian practice, from two writers separated by four centuries.
Herodotus, Book II, chapter 65: anyone who kills a sacred animal deliberately dies, and anyone who does it by accident pays whatever fine the priests decide. Then a sharp exception: “whosoever shall kill an ibis or a hawk, whether it be with his will or against his will, must die.” In Herodotus, the cat is not yet in the no-excuses category. The ibis and the hawk are.
Diodorus Siculus, writing in the first century BC, gives a harder line. In Book I, chapter 83, he says whoever intentionally kills one of these animals is put to death, “unless it be a cat or an ibis that he kills; but if he kills one of these, whether intentionally or unintentionally, he is certainly put to death”. By his day the cat had been promoted to the untouchable tier. And he explains the mechanism: “the common people gather in crowds and deal with the perpetrator most cruelly, sometimes doing this without waiting for a trial.”
That is not a statute. That is a mob, and the distinction is the one almost every retelling drops. Diodorus adds a detail that shows how frightened people were of being blamed: anyone who spotted a dead sacred animal backed away and started shouting to anybody listening that they had found it already dead.
The Roman Who Died for a Cat
The famous incident sits in the same chapter. Diodorus places it in the years before Ptolemy XII was granted the title of “friend” by Rome, which puts it shortly before 59 BC. Egypt was courting an Italian embassy and desperate to avoid giving Rome any pretext for war. One of the Romans killed a cat. The crowd went to his house. The king sent officials to plead for the man and it made no difference, the fear of Rome made no difference, and the fact that his act had been an accident changed nothing.
Then Diodorus does the thing ancient historians almost never do. He stakes his own credibility on it: “this incident we relate, not from hearsay, but we saw it with our own eyes on the occasion of the visit we made to Egypt.” Eyewitness testimony is not a legal document, but it beats a rumour, which is why the story has lasted two thousand years. Ancient records that name their own limits are rarer than they should be, a bit like the 2,200-year-old Roman service log recovered off Croatia.
The Cat Mummy Industry Was Not About Love
Herodotus gives the version everyone likes. When a cat died naturally in a house, the household shaved their eyebrows in mourning, and only their eyebrows. For a dog they shaved the entire body including the head. The dead cats went to sacred buildings at Bubastis to be embalmed and buried. He also claims that during a fire, Egyptians stood in a cordon watching the cats instead of fighting the flames, and the cats leapt over the line and threw themselves in. File that under things Herodotus was told.
What the excavated cemeteries show is a different picture. Between roughly 332 BC and 30 BC, cats were bred near temples specifically to be killed, embalmed, and sold to pilgrims as votive offerings. You did not bring your cat. You bought a cat at the gate, the way you buy a candle at a shrine. The animal was the message, and the message went to Bastet.
What the Scans Show
Researchers at Swansea University used 3D micro-CT to digitally unwrap animal mummies without opening them, including a kitten under five months old. The neck vertebrae were separated, consistent with the animal being strangled or having its neck snapped, though the team noted the separation could also have come from embalmers forcing the head upright during wrapping.
Across the votive cemeteries the age profile is the giveaway. Kittens of two to four months turn up in overwhelming numbers, partly because a small body wraps more neatly into the bundles buyers wanted. This was mass production with a supply chain, priests as manufacturers, and a customer base. Some bundles opened by modern researchers contain no cat at all, just linen, mud, and sticks, a fraud old enough to have a two-thousand-year patina on it.
The scale keeps growing. At the Bubasteion necropolis at Saqqara, a cache revealed in late 2019 included 25 wooden boxes of mummified cats, 75 wooden and bronze cat statues, and mummified lion cubs from the 26th Dynasty, the first complete lion mummies recorded from Egypt. Sekhmet’s lion and Bastet’s cat, buried in the same complex.
180,000 Cat Mummies Went to Liverpool as Fertilizer
In 1888, a farmer ploughing near Beni Hasan in Middle Egypt broke through into a cat cemetery. Estimates of what was down there range from 80,000 to over 300,000 mummified animals, mostly cats, with mongooses, dogs, and foxes mixed in.
In February 1890, roughly 180,000 mummified cats, about 19.5 tons of them, were shipped from Alexandria to Liverpool and auctioned as agricultural fertilizer. They went for around four pounds a ton. Three thousand years of embalmed sacred animals, ground up and spread on English fields. The press covered the auction as a novelty. Almost nothing was kept for study.
It is the bleakest joke in the subject. One civilisation executed people for killing a single cat. Another bought a hundred and eighty thousand of them by the ton. Archaeology has since gotten better at recognising what it is holding, as with the hundred game boards Polish archaeologists identified in a fallen Greek city in Libya, but that came far too late for Beni Hasan.
How Cats in Ancient Egypt Ended Up Everywhere Else
In 2017, Claudio Ottoni and colleagues published “The palaeogenetics of cat dispersal in the ancient world” in Nature Ecology & Evolution. They sequenced DNA from 230 ancient and modern cats spanning roughly 9,000 years, from the Mesolithic to the twentieth century, across Europe, North and East Africa, and Southwest Asia. Only six Egyptian mummies yielded usable DNA.
The result is two separate waves. Both the Near Eastern and the Egyptian populations of Felis silvestris lybica fed into the modern domestic cat, at different times. The first wave moved with Neolithic farmers out of the Near East. The second, the Egyptian lineage, expanded hard during the Classical period and spread across the Old World along maritime and overland trade routes, turning up in Mediterranean ports and as far north as a Viking-age Baltic site.
The mechanism was rats. Cats went aboard ships because ships carried grain, and grain carried rodents. The animal Egypt sanctified spread across the world as cargo insurance, moving along the same routes as the drinking customs that eventually gave us the clinking of glasses.
One more finding from the same study, and it is the one that surprises people most: the blotched tabby coat, the swirled marbled pattern you see every day, does not show up in the genetic record until the medieval period, and only becomes common after about 1300 CE. Egyptian cats were mackerel-striped. The swirls are a late arrival.
What Egypt Actually Gave the Cat
Strip out the myths and Egypt’s contribution is still enormous, just different from the one on the fridge magnet. What Egypt gave the animal was a religious identity strong enough to outlive its own civilisation, a distribution network in the form of trade shipping, and a visual vocabulary. Every stylised cat silhouette in modern design traces back to a bronze made for a temple in the Delta.
It also gave the cat a reputation it never asked for. The idea that harming a cat invites disaster survived the collapse of Egyptian religion, mutated through Greece and Rome, and reappeared in medieval Europe with the polarity flipped, at which point the cat became suspect rather than sacred. That inversion is a story of its own, covered in the history of black cat superstitions.
The cat was not consulted at any stage. It moved into grain stores, killed rodents, accepted worship, endured mass mummification, boarded ships, and ended up asleep on a keyboard four thousand years later. Same animal, same indifference. The most successful negotiating strategy in the history of domestication, and it was to do essentially nothing.
Frequently Asked Questions
Was killing a cat really punishable by death in ancient Egypt?
According to Greek sources, yes, but no Egyptian legal text saying so has survived. Herodotus records death for deliberate killing and a priestly fine for accidents, with the ibis and hawk as absolute exceptions. Diodorus Siculus, four centuries later, puts the cat in that absolute category and describes the punishment being carried out by crowds rather than courts.
Did the Egyptians domesticate the cat?
No. The oldest known deliberate cat burial with a human is from Shillourokambos in Cyprus, roughly 9,500 years old, which predates Egyptian cat imagery by thousands of years. The 2017 Ottoni study shows the Near Eastern population came first, with the Egyptian population contributing a second, later wave.
Why are so many Egyptian cat mummies kittens?
Because they were produced to order. From roughly 332 BC, cats were bred near temples and killed young for sale to pilgrims as votive offerings to Bastet. Kittens between two and four months old dominate the cemeteries, partly because small bodies wrapped more neatly into the bundles buyers expected.
What happened to the cat mummies found at Beni Hasan?
A farmer uncovered the cemetery in 1888. In February 1890, around 180,000 mummified cats, roughly 19.5 tons, were shipped from Alexandria to Liverpool and sold at auction as fertilizer for about four pounds a ton. Very little was preserved for study.
Where was Bastet worshipped?
Her cult centre was Per-Bast, called Bubastis by the Greeks, now Tell Basta near Zagazig in the eastern Nile Delta. Édouard Naville excavated the temple from 1887 and dated the main structure to Osorkon II in the ninth century BC. Cat catacombs also exist at Saqqara, in the area known as the Bubasteion.
The Short Version
Cats reached Cyprus by boat before Egypt drew its first one. Bastet arrived as a lioness and softened into a housecat over a thousand years. The death penalty is Greek testimony about mob justice, not a recovered statute, and Diodorus swore he watched it happen to a Roman. The mummies were an industry, mostly kittens, sold at temple gates, and in 1890 Britain bought a hundred and eighty thousand of them by the ton. Everything here is worse and more interesting than the poster version, and the cat, as usual, came out of it fine.
