These are kitty fastfood. You can tell them apart from the Grant's Gazelle because they have a black/white racing stripe along their sides. And they do tear around. They are close to the speed of a cheetah, and can beat one out if they have enough of a lead and the cheetah tires out. They tend to run and bounce around all day . . . at least until a cat catches up with them. Like the Grant's Gazelle, they are pretty ubiquitos.
