Werecats are highly developed creatures and are considered to be the genetic sub-species of shape shifters. A werecat is a therianthropic creature of folklore, horror, and occultism, described as being a type of shape-shifter similar to a Werewolf.
Depending on the type, the species involved can be a domestic cat, tiger, lion, leopard, lynx, or any other type of the felidae family; including some that are purely fantastical felines.
Typically, an individual werecat can only transform to one unique feline, not to a number of different species, and each individual type of werecat may be known by a more species-specific term such as "werelion".
The word "werecat" was not coined until the late 19th century, so it was not directly used in legends from earlier eras, only by later folklorists' commentary.
