Aurora, mother of the newborn polar bear cub at the Columbus Zoo, began taking breaks from caring for her cub late Thursday morning. When these breaks continued throughout the day and became longer the Zoo's Animal Care staff made the decision to remove the cub from the den and began to hand-rear the newborn. At this time the cub, a female, is healthy and feeding regularly. She weighs 1.5 pounds and gained 10 grams overnight. Staff will continue to monitor and care for her around-the-clock.
