Familiar vs Pet: What's the Difference in Witchcraft?

Not every beloved animal is a familiar. Discover the real difference between a witch's familiar and a pet, grounded in genuine witch trial history.

If you spend any time in witchcraft circles, you'll hear the word "familiar" tossed around almost interchangeably with "pet." The black cat winding round the cauldron, the raven on the windowsill, the toad tucked in a garden pot; all of them get called familiars, sooner or later. But the two things aren't the same, and the difference matters. It's the difference between an animal you love and a spirit you work with.

What a Familiar Actually Is

A familiar, in the old sense, is a spirit — not necessarily an animal at all, though it usually takes animal form because that's a shape easy for us to relate to and for it to move through. It comes to a witch (or is called by one) to assist in magical work. It has its own will, its own history, its own opinions about the task at hand. You don't own a familiar. You're in relationship with it, and like any relationship worth having, it involves negotiation, respect, and reciprocity.

This is where the historical record gets interesting. In the English witch trials of the 16th and 17th centuries, familiars show up again and again in the confessions and accusations. Usually described as small creatures (mice, toads, weasels, flies) that the accused fed from their own body, often at a mark or "witch's teat." The 1566 Chelmsford trials are some of the earliest and best documented: Elizabeth Francis testified to a white-spotted cat familiar named Sathan, inherited from her grandmother, who she claimed she fed with bread, milk, and her own blood in exchange for help with wealth, love, and revenge. By the time of Matthew Hopkins (the self-styled "Witchfinder General" who swept through East Anglia in the 1640s extracting confessions during the chaos of the Civil War), familiars had become a centrepiece of prosecution, with accused women pressured to name and describe imps until the record was full of dogs, ferrets, and birds given names like Vinegar Tom and Grizzel Greedigut. Strip away the persecution and the panic, and what's left underneath is an older folk memory: the cunning folk and hedge witches of pre-Christian and early Christian Britain kept working relationships with spirits who took animal shape, and who helped with healing, divination, protection, and the small daily magics of rural life. The court records twisted it into something monstrous, evidence of pact with the devil rather than practical craft. The practice itself was ancestral, and considerably older and stranger than the courts that tried to kill it.

The forms these spirits took were far stranger and more varied than the tidy black cat of modern imagination. Confessions describe legless spaniels, rabbits, polecats, and creatures that shifted shape entirely mid-encounter. One of the odder accounts comes from Jane Holt, a widow of Faversham, who in 1645 described a familiar that had visited her for twenty years looking exactly like a hedgehog — except when she pushed it away, it didn't feel prickly at all. It felt soft, she said, like a cat. That mismatch between appearance and texture is a small detail, but it points at something bigger: these were never really animals being described. They were spirits borrowing a shape close enough to pass, and the seams showed if you touched them.

A familiar can arrive in dreams before it ever shows up in the physical world. It can appear as an animal you've never lived with. It can be an animal spirit without a body at all; you feel it, you sense its presence at your workings, you never once see it walk on four legs. What makes it a familiar isn't fur and whiskers. It's the working bond.

This is also part of why familiars occupy a different category from flesh-and-blood animals in older traditions. Some folk beliefs held that certain spirit familiars could endure and regenerate in ways no physical creature could — a mark of their nature as spirit rather than body, and part of what made them useful, and endurable, for the harder edges of spellwork. It's a strange thread in the old lore, and one more reason the physical pet and the working spirit were never really the same thing to begin with.

What a Witch's Pet Is

Your pet, on the other hand, is simply the animal who shares your home and your life. They might curl up while you're blending oils, sit by the altar because it's a warm spot in a sunbeam, not because they've clocked in for spiritual duty. Loving your animals, letting them near your craft, feeling comforted by their presence during ritual — all of this is real and good and doesn't require them to be anything other than what they are: your companions.

Here's the part worth being precise about: a living pet does not become a familiar simply by being present for your workings, however attentive or attuned they seem. A familiar is a spirit. Your pet, however sensitive and however dear, is a living creature first. The two categories don't blur just because the bond is close.

Where the line does get interesting is death. Some traditions hold that an animal companion, once passed, may return as a spirit and take up a working role it never held in life — arriving now as something closer to what we'd call a familiar, no longer bound to a body. That's a different thing entirely from a living pet being reclassified because they sit nicely by the altar.

It's also worth saying plainly: not every witch has a familiar, and that's not a failing. The relationship isn't owed to anyone, and it isn't summoned by wanting it.

Some Old Signs Folk Traditions Point To

Folklore across Britain and Europe offers a few threads worth holding loosely, not as rules but as things to notice:

An animal who seems to arrive at an unusually significant moment — during a life change, grief, a new phase of practice
A creature who reacts to your workings specifically, rather than to noise or movement generally
A presence that feels attentive in a way that goes beyond ordinary animal awareness
Dreams or visions of an animal guide before it appears, or that never appear in physical form at all

None of these are proof on their own. Discernment matters more than checklists here. Sit with it. Ask. Listen for what comes back.

Why the Distinction Matters

Part of tending any craft with sincerity is not flattening its language. If every pet becomes a "familiar" simply because they're loved and present, the word loses its meaning, and so does the specific, old, working relationship it once described. Your cat can be entirely themself; beloved, ordinary, uninterested in doing your bidding magically, yet still be sacred to you. And if you do have a working spirit at your side, animal-shaped or otherwise, that relationship deserves to be named for what it is: a partnership with its own history, stretching back through the hedge witches and cunning folk who kept these same quiet alliances long before any of us were here.

Whichever one is curled up beside you tonight, they're worth honouring on their own terms.
