KidsPost helps you keep track of the seven cubs to the zoo's lion yard.
Nababiep, left, is seen as her cub, Aslan, and a cub from another mother, Zuri, right, show interest in a box that carried a present for a first-birthday celebration for the seven lion cubs at the Smithsonian National Zoological Park. Four cubs were born Aug. 31, 2010, and three were born Sept. 22, 2010. The cake given to the lions was made of ice, two whole cow femurs cut in half, five pounds of shaved beef and a half-gallon of cow blood. Matt McClain/FOR THE WASHINGTON POST Buy Photo
