The hedgehog's back contains two large muscles that control the position of the quills. The average hedgehog has about 5,000 to 6,500 quills that are strong on the outer surface but filled with air pockets on the inside. When the creature is rolled into a ball, the quills on the back protect the tucked head, feet, and belly, which are not quilled.
Hedgehogs are individuals, so some are more vocal than others. Hedgehogs make a variety of sounds as part of their way of communicating. Each of these sounds has a different meaning. Happy, content hedgehogs make a gentle purring sound, not unlike that of a cat.
