[5] In the past, the cheetah was often called "hunting leopard" because they could be tamed and used for coursing. [18][19], In 1975, five subspecies were considered valid taxa: A. j. hecki, A. j. jubatus, A. j. raineyi, A. j. soemmeringii and A. j. [67][105] Playing can improve catching skills in cubs, though the ability to crouch and hide may not develop remarkably. [47][48] A prominent instance was the deadly feline coronavirus outbreak in a cheetah breeding facility of Oregon in 1983 which had a mortality rate of 60%—higher than that recorded for previous epizootics of feline infectious peritonitis in any felid. This reduces the risk of losing balance during runs, but compromises the ability to climb.
