On a serious note years ago I was in a zoo. As everyone knows the big cats in captivity deteriorate because they are not leading the alpha hunting life. I was looking at the mountain lion cage and they had three of them in them. Unlike the African cats in the zoo they looked in shape. The mountain lions looked about 150lbs to 200lbs. The zoo keeper threw in a couple of giant steaks on the opposite side of the caged in area. These mountain lions exploded. They looked like they went from zero to 40MPH in two steps. I just pictured them going for a man's neck with that speed.
