While shooting cheetahs at Masai Mara Nature Reserve, I came across a pair of cheetahs stalking prey. The initial two attempts went in vain and they appeared desperate to make a kill. Few impalas were seen nearby, and they started stalking the impalas who were apparently unaware of their presence. Some baboons were also nearby and the cheetahs waited patiently. As soon as the baboons left, they made a short sprint and grabbed an impala and to my surprise they started devouring it with the impala still being alive. They probably wanted to finish before the baboons, who are well known to steal cheetah kills, arrive again.
