The Abyssinian is one of the oldest known breeds. In appearance, Abyssinians resemble the paintings and sculptures of ancient Egyptian cats which portray an elegant feline with a muscular body, beautiful arched neck, large ears and almond shaped eyes. Abys today still retain the jungle look of felis lybica, the African wildcat ancestor of all domestic cats.
