National Zoo’s Cheetah Cubs at Play
Image by Smithsonian’s National Zoo
Both cheetah cubs born at the Smithsonian Conservation Biology Institute, the National Zoo’s facility in Front Royal, Va., are thriving.
The older cub, a male, was born on Dec. 6, 2010 to Amani. The younger cub, a female, was born on Dec. 16, 2010 to Zazi.
How to identify the cubs: The male cub is slightly larger than the female and has a prominent white mantle (the hair that runs along a cheetah cub’s spine).
