Cheetah musairia was attacked by a lioness and was able to counter the lioness so as to get her attention away from her cubs in which she succeeded just before the mara rangers intervened and scared the lioness away.
Sometimes I agree with intervention by humans: cheetahs are on the brink of extinction also because of humans (poachers, farmers defending their livestock, reducing habitat,…). Every single loss of a cheetah (cub or adult) is a tragedy.
