Bottle soothes baby: Like any other eight-week-old baby; a polar bear cub finds a bottle of milk the pause that refreshes. The two cubs at the Metro Zoo; orphaned when a hunter shot their mother in the Northwest Territories; sleep after their bottle feedings; which are sheduled every three hours. Inuit children have named the cubs Sanikiluaq and Pisitik after an Inuit hunter and the Inuit word for hero.
