Black Panther Momma and Cub! A black panther cub is usually born in the same litter along with other light-colored leopard cubs. Typically, a leopard litter consists of two to three cubs but, sometimes, up to six. Black panther cubs are born with their eyes closed and are covered with faintly spotted smoky gray fur. They weigh about 450 to 1000 g (16 to 35 oz).
