Based on the reference pictures below:
This was an email my father sent me on o9.26.2o1o:
Michel Denis-Huot took these photos in Masai Mara, a Kenyan safari: "These three cheetah brothers libing together since they left their mother at about 18 months old. One morning we saw them, they seemed not to be hungry, walking quickly but stopping sometimes to play together. At one point, they met a group of impala who ran away. But one youngster was not quick enough and the brothers caught it easily."
