Ablack cat is adomestic cat with black fur. They may be a specificbreed, or a commondomestic cat of no particular breed. Most black cats have goldenirises due to their highmelanin pigment content. Black cats are the subject ofmythology, legend, and superstition. They are often associated withwitches and good or bad luck inEuropean folklore.
TheCat Fanciers' Association (CFA) recognizes 22 catbreeds that can come with solid black coats.[1] TheBombay breed is exclusively black.
Any cat whose fur is a single color, including black, is known as a "solid" or "self". A "solid black" cat may be coal black, grayish black, or brownish black. Most solid-colored cats result from a recessive gene that suppresses thetabby pattern. Sometimes the tabby pattern is not completely suppressed; faint markings may appear in certain lights, even on a solid black cat. A cat having black fur with white roots is known as a "black smoke".[2]


Black cats can also "rust" in sunlight, the coat turning a lighter brownish-red shade.[2] Eumelanin, the pigment required to produce the black fur, is somewhat fragile, so the rusting effect can be more pronounced in cats that frequently spend time in the sun. A rarer situation that can also cause rusting is a deficiency of the amino acidtyrosine, which is required to produce eumelanin.[3]
In addition to theBombay, theCat Fanciers' Association allows solid black as a color option in 21 other breeds. The color description for those breeds is:

The superstitions surrounding black cats vary from culture to culture, and black cats have positive associations in theCeltic nations and England, where a black cat crossing one's path is considered good luck.[5][6] In 2014, the animal welfare organisationRSPCA stated that "in UK folklore, black cats symbolise good luck".[7]Scottish lore holds that a black cat's arrival at a new home signifies prosperity, whileWelsh lore states that a black cat brings good health:

A fedr swyno hefyd,
A chadw'r teulu lle mae'n byw
O afael pob rhyw glefyd.
A black cat, I've heard it said,
Can also charm,
And keep the family where it lives
From the grip of every kind of sickness.
TheGaels had traditions of feral and sometimes malevolent black cats.[citation needed] InScottish mythology, afairy known as theCat sìth takes the form of a black cat with a white spot on its chest.

Since the 1880s, thecolorblack has been associated withanarchism. The black cat, in an alert, fighting stance was later adopted as ananarchist symbol.
More specifically, the black cat—sometimes called the "sab cat" or "sabo-tabby"[16]—is associated withanarcho-syndicalism, a branch of anarchism that focuses onlabor organizing, including the use ofwildcat strikes anddirect action tactics.
According toRalph Chaplin, who is generally credited with creating theInternational Workers of the World's black cat symbol, "My 'Sab Cat' was supposed to symbolize the 'slow down' as a means of 'striking on the job'," although others in the IWW used the symbol much more broadly.[17] In testimony before the court in a 1918 trial ofIndustrial Workers of the World leaders, Chaplin stated that the black cat "was commonly used by the boys as representing the idea ofsabotage. The idea being to frighten the employer by the mention of the namesabotage, or by putting a black cat somewhere around. You know if you saw a black cat go across your path you would think, if you were superstitious, You are going to have a little bad luck. The idea of sabotage is to use a little black cat on the boss."[18]

There is a common myth that black cats are the least likely to be adopted from animal shelters. This remains widely debated and studies have resulted in conflicting outcomes.[26][27]
Some shelters suspend or limit adoptions of black cats aroundHalloween[28] for fear they will be tortured, or used as "living decorations" for the holiday and then abandoned.[29][30][31] Despite this, no one has ever documented in the history of humane work any relationship between adopting black cats and cats being killed or injured. When such killings are reported, forensic evidence has pointed to natural predators, such ascoyotes,eagles, orraptors as the likely cause.[30] Limiting or suspending adoptions around Halloween also places more cats of all colors at risk of dying in shelters due to overcrowding.[32]
October 27 has been designated 'Black Cat Day' byCats Protection in theUnited Kingdom,[33] to celebrate the virtues of black cats and to encourage people to adopt an unwanted black cat. Cats Protection's own figures suggest that black cats are more difficult for them to find a new home for than other colors.[33] In 2014, theRSPCA reported that 70% of the abandoned cats in its care were black, saying that though black cats symbolise good luck in UK folklore, one reason for the high percentage of black cats in its care was that black cats tend not to photograph as well.[34]

In 2014Toronto, Canada's largest city, held an event onBlack Friday during which people could adopt a black cat without paying the usual $75 adoption fee, in order to encourage the adoption of black cats.[38] This trend has now spread across the United States, with many shelters offering free adoption of black cats on Black Friday.
With the success of the 2018 African-themedsuperhero film,Black Panther, there was a fad of adopting black domestic cats as pets and naming them after various characters of the film, such asT'Challa andShuri.[39] It has been observed that usually people were not going out of their way to follow this fad, but visited animal shelters to simply adopt a pet under normal circumstances and were inspired by theBlack Panther to adopt a black cat when they see one. Regardless, as much as this was a welcome development for pets that are difficult to get adopted, to reduce the chance of such cats being abandoned when the fad fades, reputable animal shelter personnel took the usual precautions of having potential adopters fill out questionnaires to weed out potentially abusive guardians and have them read literature about the needs and responsibilities of such a pet to dissuade the less conscientious.[40]
