 Being both unusual and conspicuous, albino Leopards would have fallen victim to big game hunters' guns.A white, but apparently not albino, leopard cub born in Africa was sold to a zoo in Japan in the spring of 1999 and is called "Nana".Two Leopard cubs were born at the Wildlife World Zoo in Arizona; one, named "Isis" was believed to be the only white Leopard to be born in captivity.
