Lions inhabited the western hills of Westeros. In antiquity, lions made dens in Casterly Rock itself and some were owned by the Kings of the Rock. According to a semi-canon source, some of King Loreon I Lannister's lions broke free and slew three of his sons, some say as a curse from Morgon Banefort.
Wild lions were seen during the reign of Lord Tytos Lannister, as the first knight of House Clegane saved Tytos from a lioness and lost a leg and three dogs in the effort. Cersei Lannister recalls several caged lions kept in the bowels of Casterly Rock during her childhood, a legacy of her grandfather Tytos's time.
