The cheetahs at the National Zoo were quite active.  Interesting, the zebra exhibit was right next door and the cheetahs often they lingered along the fenceline.  Apparently they usually attack animal under 100#s, accelerate from 0-60 mgh in three seconds, and bound 29 feet between strides at full speed.

Not exactly the savannah...
