A black cat is a domestic cat with black fur that may
be a specific breed, or a common domestic cat of no particular or mixed
breed. All-black fur pigmentation is slightly more prevalent in male
cats than female cats. Most black cats have golden irises due to their
high melanin pigment content. Black cats are the subject of myth,
legend, and superstition. They are often associated with witches and bad
luck in European folklore.
Some shelters suspend or limit adoptions of black cats around Halloween
for fear they will be tortured, or used as
"living decorations" for the holiday and then abandoned.
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 as coyotes, eagles, or raptors as the likely
cause. Limiting or suspending adoptions around Halloween also places
more cats of all colors at risk of dying in shelters due to
overcrowding.
