In this Dec. 31, 2012 photo, Johari, a 3-and-half-year-old female cheetah, chases after a mechanized toy during a performance on the Cheetah Run at Safari Park, in Escondido, Calif. While moving at high speed, Johari is not at full speed, evidence by the fact her ears are visible. Cheetahs use their tails like a rotor to balance while they are running. (AP Photo/Lenny Ignelzi)
