A black cat is a domestic cat with black fur that may be a mixed or specific breed, or a common domestic cat of no particular breed. The Cat Fanciers' Association (CFA) recognizes 22 cat breeds that can come with solid black coats.[1] The Bombay breed is exclusively black. 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. In popular myths, witches are believed to be associated with black cats.
Black cats can also "rust" in sunlight, the coat turning a lighter brownish-red shade.[2] Eumelanin, the pigment that is 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 acid tyrosine, which is required to produce eumelanin.
Black Cat (Felicia Hardy) is a fictional character appearing in American comic books published by Marvel Comics. Throughout her history, Black Cat has sometimes been an enemy, love interest, and ally of the superhero Spider-Man. Created by writer Marv Wolfman and artist Keith Pollard,[5] she first appeared in The Amazing Spider-Man #194 (July 1979).[6]

Felicia Hardy is the daughter of Walter Hardy, a world-renowned cat burglar. After suffering from a traumatic assault by an ex-boyfriend as a college freshman, she trained herself in various fighting styles and acrobatics and, after deciding to follow in her father's footsteps, adopted the costumed identity of the Black Cat.[7] She has the subconscious ability to affect probability fields, producing "bad luck" for her enemies. The character was originally depicted as a supervillain and adversary of Spider-Man, but over time the two fell in love, which motivated her into becoming both an antiheroine, and his partner. However, their relationship grew complicated after it became apparent that Black Cat was only attracted to the alter ego of Spider-Man and had little interest in the hero's civilian life as Peter Parker. After their break-up, Black Cat maintained her role as one of Spider-Man's most trusted allies and for years the pair shared an on-again, off-again romance.

Being a part of his supporting cast and one of his principal love interests, Black Cat has been featured in many media adaptations related to Spider-Man, including animated series and video games. Felicity Jones played Felicia Hardy in the 2014 film, The Amazing Spider-Man 2. IGN ranked her as Spider-Man's 24th greatest enemy in 2014.[8]
