Two cheetahs, a mother and daughter, gave birth to large litters in the same week at the Smithsonian Conservation Biology Institute in Front Royal, Virginia, an adjunct of the National Zoo. One was a litter of five; the other cheetah gave birth to seven cubs, but the smallest two did not survive. The remaining ten cubs are doing just fine, and will spend the next 18 months in Virginia. After that, they'll go to other zoos or breeding programs.
The sound on this video begins about halfway through, but even then you'll have to listen closely to hear the tiny cubs hiss. Learn more about the National Zoo's cheetah breeding program at Smithsonian.
