The cheetahs were just roaming across the wilderness, when they spotted a pack of Impalas, which they decided to chase. One little antelope wasn’t fast enough and got left behind. When the cheetahs caught up with it, they simply started playing with what supposed to be their food. The three felines started licking the Impala, put their paws on its head, cuddling, but nothing threatening.
After a playing session, the Impala ran away unharmed. The only remotely logical explanation is that the three cheetahs were already too full and tired for another kill.
