Black cat

A black cat is a domestic cat with a black coat.

Updated September 11, 20261 min readCited sources

A black cat is a domestic cat with a black coat. Despite common belief, black cats are not a distinct breed but a coat colour found in many breeds.

Genetics and appearance

Black coat colour in cats is caused by high melanin production. Most black cats have golden or yellow irises due to this melanin. Black cats are not a separate breed; many breeds can produce black coats.

Folklore and superstition

In European folklore, black cats have been viewed as omens of either good or bad luck. They are often associated with witches and have become symbols of Halloween. These superstitions vary by culture.

Recognized breeds

The Bombay cat is the best-known breed that is always black. However, several other breeds recognized by the Cat Fanciers' Association can also have solid black coats.

In short

  • Black cats are domestic cats with black fur, not a breed.
  • High melanin gives many black cats golden eyes.
  • They are central to European folklore and superstition.
  • The Bombay is a breed that is always black.
Canadian angle

Black cats are commonly discussed in Canadian pet adoption, animal welfare, and Halloween-related folklore contexts, but they are not uniquely Canadian.
