If you tune into the Smithsonian’s National Zoo and Conservation Biology Institute's Cheetah Cub Cam, you might see one or two cubs playing in the den. The cubs are starting to play independently. When cheetah biologist, Adrienne Crosier, tuned into the cam in mid-January, she witnessed this female cub rolling around and having a ball in the den all on her own. https://nationalzoo.si.edu/webcams/cheetah-cub-cam | ZooBorns
