The Cheetah Conservation Center at the San Diego Zoo Safari Park is one of 10 U.S. breeding facilities for the South African cheetah, and there is a lot that makes this species of feline so special. Tune in to learn about their cleat-like toenails, amazing vision, and how they are not quite a big or small cat.
