In addition, the hedgehog picks up needles by carefully folding them on its back.

After mating, the hedgehog leaves the hedgehog and goes to equip the hole, or deepen and expand the old dwelling. Pregnancy in a female lasts 7 weeks. At one time, a hedgehog is born from 2 to 6 hedgehogs. Little eared hedgehogs are completely blind when they are born. The hedgehog's eyes open only after 2 weeks, the cubs feed on mother's milk.
