A zoo in Richmond, Virginia is celebrating the birth of six cheetah cubs, now three months old and able to be seen at the zoo's public cheetah habitat. The cubs, three males and three females, spent their first three months a the Metro Richmond Zoo receiving care privately at the zoo's Cheetah Conservation Center before being moved to the public cheetah habitat. Video shows the cubs engaging in playful behavior together as their mother watches over them, and gets playfully involved at times, too. Metro Richmond Zoo says that cheetahs face a range of threats in the wild, and the species' population has declined by 93% over the last 120 years. It also says that cheetahs are Africa’s most endangered big cat. It also says that in a little over a decade, 167 cheetahs have been born at the zoo, establishing it as a U.S. leader in cheetah conservation and care.
