Black cats are considered bad luck in Western folklore mostly because of a single medieval decision. In 1233 CE, Pope Gregory IX issued a proclamation linking black cats to the devil, and that idea fused with the witch hunts of the following centuries, when people believed witches could shapeshift into black cats. That is the whole origin story. There is no evidence a black cat crossing your path causes anything at all, and in several cultures, including the UK and Japan, a black cat is actually a sign of good fortune. Below, we separate the real history from the myths, and look at what the data actually says about black cats today.
Why Are Black Cats Considered Bad Luck in the First Place?
The superstition is almost entirely a European invention. As the Catholic Church expanded its power in medieval Europe, it began treating folk healers and so called witches as competition, and black cats got pulled into that fight. Because a black cat's dark coat let it blend into shadows and look genuinely spooky at night, it became the go to symbol for witchcraft and evil in a way that orange or white cats never did. By the time the panic peaked, a black cat crossing your path was read as a bad omen, not because of anything the cat did, but because it might be a witch in disguise.
None of that has any basis in fact. A cat's coat color comes down to a single gene (the same one responsible for orange, tabby, and tuxedo patterns) and has zero connection to luck, temperament, or supernatural activity.
Is It True Black Cats Are Harder to Adopt?
This is the myth we hear most from customers, and the honest answer is that the data is mixed. One urban shelter study found black cats had the lowest adoption rate and the highest euthanasia rate of any coat color, and spent 6 to 8 days longer in shelters than other cats. But broader data compiled by the ASPCA tells a different story: black cats actually made up 31 percent of cat adoptions, compared to 20 percent for gray cats and 18 percent for brown cats, which contradicts the idea that black cats are passed over across the board.
The likely truth sits in between: outcomes vary a lot by shelter, region, and even how a cat is photographed, since black cats are notoriously hard to photograph well under fluorescent shelter lighting. That is part of why the ASPCA runs Black Cat Appreciation Day every August, using better photography and reduced adoption fees to help black cats get noticed.
A love letter to every black cat who has ever judged you silently from across the room.
Where Are Black Cats Actually Good Luck?
The bad luck superstition is not universal, and it is not even consistent within the same countries. In the UK, folklore actually flips the American version: a black cat crossing your path is said to bring good fortune, not bad. In Japan, black cats are considered lucky, especially for people looking for a partner, and maneki neko (the "lucky cat" figure) has roots in this same tradition of cats as good omens. In parts of Russia, all cats, black ones included, are viewed as signs of prosperity and are welcomed into a new home first, before the humans move in.
So the "bad luck" label is really a regional cultural artifact, not a global truth, and definitely not a fact about the cat.
Common Black Cat Myths vs the Facts

|---|---|
| A black cat crossing your path means bad luck. | This is a Western superstition dating to 1233 CE. In the UK and Japan, the same crossing is considered good luck. |
| Black cats are witches in disguise. | A medieval belief with no basis in reality. Coat color is determined by a single pigment gene. |
| Black cats are never adopted. | ASPCA data shows black cats made up 31 percent of adoptions, more than gray or brown cats. |
| Black cats have a different personality. | No study has linked coat color to temperament in domestic cats. |
| Black cats fade or turn brown with age, so something is wrong. | A slight rusty tint in sunlight is normal pigment behavior, not a health issue. |

Do Black Cats Actually Behave Any Differently?
No. Every documented cat behavior, from head bumps to 3 a.m. zoomies, shows up across every coat color at the same rates. What black cats do have going for them is a practical one: their coat hides shedding and stains better than lighter fur, which is a real, if unromantic, reason a lot of cat parents specifically seek them out. If your cat happens to be black, the only thing genuinely special about their coloring is that it made them a target for a superstition that has nothing to do with who they actually are.

Frequently Asked Questions
Why are black cats considered bad luck in America but good luck in the UK?
Both superstitions trace back to European folklore, but they diverged over time. American bad luck beliefs came largely from the same medieval witch associations that spread through colonial era Europe, while British folklore kept an older, competing tradition where a black cat crossing your path is a sign of good fortune headed your way.
Are black cats actually adopted less than other cats?
It depends on the shelter. Some studies show lower adoption rates and longer shelter stays for black cats, while ASPCA compiled data shows black cats making up a larger share of adoptions than gray or brown cats. Photography, lighting, and individual shelter practices seem to matter more than the coat color itself.
Is it true black cats are more aggressive or unfriendly?
No. There is no scientific link between coat color and temperament in domestic cats. Personality is shaped by genetics, early socialization, and environment, not fur pigment.
Why do black cats get associated with Halloween?
The Halloween connection comes from the same medieval witch folklore, since Halloween evolved from Samhain, a festival associated with spirits and the supernatural, and black cats had already been tied to witches for centuries by the time the holiday took its modern shape.
Do black cats' coats change color as they age?
Some black cats develop a faint reddish or rusty tinge in strong sunlight, which is a normal pigment reaction and not a sign of illness. A vet visit is only needed if you notice actual bald patches, scabbing, or skin irritation.
