It was a risky birth three weeks ago in northern Virginia, now the cubs are at the Smithsonian's National Zoo in Washington, D.C.

The cubs will now be raised by hand after being transported to their new home. They were born three weeks ago after a scary start.

Their mom, 5-year old Ally was a first time mom and after the birth of her first cub in late April thing's were notably wrong. She abandoned her first cub and although there were three more to come, her labor stopped. The staff present at the birth stepped in and performed an emergency caesarean section. They were able to save one of the cubs and Ally.
