There are few images more recognisable than a witch with a black cat. It has become such a familiar part of Halloween that we rarely stop to wonder where the idea actually came from. Why a cat? And why, in particular, a black one?
The connection between cats and witches isn't rooted in one particular story or event. Instead, it developed gradually through folklore, historical beliefs about witchcraft and familiars, and later through books, illustrations and popular culture. Cats already had a long and varied history alongside humans before they became part of the familiar image of the witch.
And, when you think about it, they were probably always going to make good characters in a witchy story. Cats are independent, often active at night and perfectly capable of appearing beside you without making a sound. They have a habit of watching things we can't see and disappearing just when you start wondering where they've gone.
Whether there's anything mysterious about them is another question entirely.
Cats Before the Witches
Cats have lived alongside humans for thousands of years, and their place in different cultures has varied enormously. They haven't always been associated with darkness or witchcraft; in fact, some of the earliest cultural associations with cats were quite different.
In ancient Egypt, for example, cats were associated with the goddess Bastet, who was commonly represented with feline features. Archaeological discoveries also show that cats had an important place in aspects of ancient Egyptian religious and domestic life.
Elsewhere, cats were valued more practically as hunters of rodents and became familiar animals around farms, homes and ships. Their role was often simply that of a useful companion living alongside people.
The association with witches belongs to a much later tradition of European folklore. As ideas about witchcraft and the supernatural developed, cats became one of the animals that appeared in stories about witches and their supposed supernatural companions.
The Story of the Familiar
To understand the witch's cat, it helps to understand the idea of a familiar.
In historical accounts of witchcraft, particularly those from early modern Europe, a familiar was sometimes described as a supernatural companion or spirit that assisted a person accused of witchcraft. Accounts varied, but animals were sometimes said to take on this role, with cats among those mentioned.
These stories were part of the beliefs and accusations surrounding witchcraft at the time. They shouldn't be confused with evidence that animals actually had supernatural abilities or that people really possessed magical companions.
Nevertheless, the idea proved remarkably memorable. Once the image of a witch and her animal companion appeared in stories and illustrations, it became a natural part of the wider folklore surrounding witchcraft.
Cats were particularly well suited to the role.
Why Cats?
There isn't one definite answer to why cats became so prominent in these stories, and it's probably better not to pretend there is. Their behaviour, however, may have made them particularly interesting to people living in societies where folklore and supernatural explanations were a part of everyday life.
Cats are naturally independent. They are often active after dark, move quietly and can come and go without much human involvement. Unlike dogs, they don't tend to announce where they're going or what they're doing. They simply disappear and reappear when they feel like it.
Today, we'd recognise all of that as normal cat behaviour.
In earlier periods, though, an animal that was active at night and seemed to have a life of its own could easily become the subject of stories and superstition. A cat appearing unexpectedly in a village at night was still just a cat, but folklore has a way of turning ordinary moments into something a little more mysterious.
Why the Black Cat?
The black cat eventually became particularly associated with witches, although the history of black cats is far more complicated than the Halloween version suggests.
Black cats appeared in some historical accounts and representations connected with witchcraft and supposed familiars. Their dark colouring may also have fitted existing cultural associations with night, darkness and the unknown.
But it's important to remember that black cats haven't had the same meaning everywhere. Different cultures and periods have associated them with everything from good fortune and prosperity to bad luck and superstition.
There is no universal meaning attached to a black cat.
The image we recognise today has been shaped by many different stories and traditions over time, with later books, artwork and popular culture helping to turn the black cat into one of the most recognisable symbols of Halloween.
What Was a Witch's Familiar?
The word familiar has become almost inseparable from the traditional image of a witch, but the historical idea was more complicated than the modern version suggests.
In some early modern accounts, familiars were described as spirits or supernatural beings that could appear in animal form. Cats, dogs, birds and other animals could all feature in these stories. The details varied considerably depending on the account and the period in which it was recorded.
Some accounts portrayed familiars as helpers, while others connected them with darker supernatural beliefs. These ideas formed part of wider European beliefs about witchcraft, religion and the supernatural.
It's worth remembering that many of the surviving descriptions come from accusations, trials and writings produced in societies with very different ideas about witchcraft from those we have today. They tell us much more about the beliefs and fears of the people who recorded them than they do about the animals themselves.
From Folklore to Pop Culture
Over time, the image of the witch's cat became increasingly familiar. Printed pamphlets, illustrations, stories and later literature helped establish a visual language around witches, with animals appearing alongside them as companions or familiars.
Eventually, the image became less frightening and more playful.
The witch's cat moved from folklore into books, films, artwork and Halloween decorations. The black cat became shorthand for mystery, magic and the supernatural, even for people who knew little about the history behind the symbol.
That's probably why the image still works so well today. You don't need to know anything about historical witchcraft to recognise a black cat sitting beside a witch as an unmistakably witchy image.
Perhaps Cats Were Always Going to Become Witchy
There is something about cats that makes them particularly easy to imagine in folklore.
They spend a surprising amount of time awake while we're asleep. They sit quietly and observe. They can move around a house without making much noise, and they seem entirely comfortable doing things on their own terms.
Anyone who has ever lived with a cat will probably recognise the feeling of wondering what exactly is going on inside their head.
Of course, there is almost always a perfectly ordinary explanation. Your cat isn't communicating with spirits; they're probably watching a tiny insect that you haven't noticed.
But folklore isn't really about proving whether something is true. It's about the stories people tell, the meanings they attach to ordinary things and the way those stories get passed from one generation to the next.
And the story of the witch's cat has certainly lasted.
The Witch's Cat Today
Today, the connection between cats and witches is largely a cultural one. The black cat has become a familiar part of Halloween and witchy aesthetics, appearing alongside moons, stars, tarot cards, candles and other symbols associated with the mysterious and supernatural.
For some people, the appeal lies in the folklore and history. For others, it's simply the aesthetic: a black cat curled up beside a candle, sitting in a moonlit window or appearing as a silhouette against an old stone wall.
Perhaps that's why the image has remained so enduring.
Cats don't need to be magical to feel a little mysterious. They've been quietly doing their own thing alongside humans for thousands of years, and we've spent just as long trying to work out exactly what they're thinking.
Maybe that's the real reason they make such perfect companions for witches.
They've always seemed to know something we don't.
