When hedgehogs hunt for food -- sometimes in hedges -- they often grunt, kind of like a hog. This explains their name. When it comes to food they might eat anything. They prefer insects, but they also won't often pass up other types of food if it presents itself.
Even though some hedgehogs are no bigger than a tea cup, don't think they can't protect themselves. They can roll up into a ball, exposing their spines to scare away predators. Before they stop, drop and roll into a ball, they may speed up their pace to rates of six feet per second to escape.
They also spend their days rolled up into a ball, sleeping. Then, they prowl around at night, looking for stuff to eat.
