“If you cross paths with a black cat, nothing in particular happens.”

This WHO fact sheet is not about black cats specifically, but it illustrates the broader point that beliefs and interpretations can vary widely across cultures and individuals. It provides context for why a superstition may be meaningful in one setting and irrelevant in another, without making any claim that a black cat crossing has no effect.

AP reporting on black cat superstition commonly notes that some traditions treat a black cat crossing your path as good luck while others treat it as bad luck. That reporting is relevant because it shows the claim “nothing in particular happens” is a dismissive interpretation rather than a documented fact about the superstition itself.

In some cultures, black cats are viewed as causing bad luck. This may partially explain why it takes longer for black cats to be adopted from animal shelters. ... Examples include the following quotations: “It is bad luck to see a black cat”; “If you see a black cat at night, walk away, or you’ll have bad luck”; “If you see a black cat, spit three times at it and you won’t have bad luck”; “If a black cat comes to your door, bad luck. The blacker the cat, the blacker the luck.”

Discussing classic work on superstition, the APA notes that people often “see connections between their actions and outcomes that are actually due to chance,” leading them to adopt rituals and omens that “do not in fact influence the results.” The article describes this as an “illusion of control,” explaining that superstitious behaviours can reduce anxiety but “have no causal power over external events.”

“Black cats are considered unlucky in some cultures because of superstitious beliefs that have been passed down over time… The association of black cats with witches (and bad luck) may stem from Western demonology, in which they were often depicted as familiars of witches… In many Western cultures, black cats signify bad luck much like Friday the 13th and certain warned‑against activities do.

"Myth: It’s bad luck when a black cat crosses your path." The article says the rumor began in Europe during the Middle Ages and concludes, "Needless to say, there was no truth behind it then or now."

“Throughout the Middle Ages, black cats were often portrayed in folklore and art as companions or even shapeshifted versions of witches. Over time, this led to a widespread superstition that a black cat crossing your path was an omen of bad luck or even death… These beliefs persisted in parts of Europe and colonial America well into the early modern period.”

Bad omens surrounding black cat crossing the road or treating them as “bad luck” is nothing but superstition. This superstition goes back thousands of years. ...

“In western Wiccan practices it is said that a black cat crossing your path foretells misfortune and death, and this is the predominant superstition surrounding black cats… Superstitions are learned behaviours displayed in times of uncertainty, with rarely any logical or rational grounds for the action being completed… Ultimately superstitions, and rituals relating to superstitions, are about alleviating anxiety in relation to uncertainty, introducing an element of perceived control into situations where we feel out of our depth or anxious.”

The article says the superstition that a black cat crossing your path was bad luck emerged from medieval beliefs linking black cats with Satan and witchcraft. That is evidence that the event has been culturally interpreted as significant, not as something that “nothing in particular” happens to.

Britannica defines superstition as “a belief or practice resulting from ignorance, fear of the unknown, trust in magic or chance, or a false conception of causation.” Examples given include “omens, charms, and rituals thought to influence luck or avert misfortune,” but it emphasises that such beliefs lack rational or scientific basis: they “persist despite evidence to the contrary and are not supported by demonstrable causal mechanisms.”

In English-language folklore, a black cat crossing your path is commonly treated as a superstition: in some regions it is considered bad luck, in others good luck.
