Observations on two groups of cheetahs for one and three nights respectively revealed unusual and unrecorded behaviour. Both group compositions exposed unexpected social interactions. One group scavenged meat from a one-day-old carcass and the other hunted during dark-moon nights. Three cheetahs captured four springbok in two nights and lost them all to other large carnivores. Observations during three hunts suggest a degree of group hunting. Keywords: carnivores, cheetah, group composition, hunting behaviour, scavenging.
