The wild cat (Felis silvestris), sometimes "wildcat" or "wild-cat" especially when distinguishing from other wild species of felines, is a small predator native to Europe, the western part of Asia, and Africa. It is a hunter of small mammals, birds, and other creatures of a similar size. There are several subspecies which occur in different world regions, including also the ubiquitous domestic cat (Felis silvestris catus), which has been introduced to every habitable continent and most of the world's larger islands, and has become feral in many of those environments.
