You all should watch National Geographics Predators at War. It was on ondemand on the National Geographic channel and showed how desperate predators get when there is a drought. It was pretty awesome. It had Lions, Hyenas, Leopards, Cheetahs, Wild Dogs and Vultures all fighting each other. The camera man was pretty brave, he got within feet of feeding Hyenas. Also a pack of Lioness was approaching him at night and he was able to scare them away with some sound he made.
This was the first time I saw a starving Cheetah fend off a Hyena. As most know, the Cheetah is at the bottom of the pecking order and is not built for fighting.
