I want to write about Cheetahs. Even though cheetahs can reach almost 100 miles an hour, they cannot go for long without stopping and resting.  Instead of roaring from a distance and charging, they sneak up really close, then attack.  It gives their prey less chance of escaping. If the cheetah was still evolving from, lets say, a dog, it would die right after it caught its food. Because at the speed a cheetah goes, it needs more air so it can breathe better.  william james clemons age10
