A growing number of American homes are keeping African pygmy hedgehogs(刺猬) as pets. Hers are some questions and answers about the small animals whose backs and sides are covered with about 6,000 quills. Their quills are short, but hard and sharp.

Where do they come from?

The breed is a hybrid (杂种) of the four-toed hedgehog or African white-bellied hedgehog and the Algerian hedgehog. Its natural habitat is central, eastern and southern Africa. It now breaks the law to bring them into the United States.

An adult African pygmy hedgehog is 6 to 11 inches long and weighs 1 to 2 pounds. A relaxed one is generally oval (椭圆的) , with a very short tail and short limbs that keep the body close to the ground . When threatened or frightened, it rolls into a ball and forces its quills out in all directions. Female hedgehogs are a bit larger than the male ones. The face and the underside are covered with soft and white fur.

What do they eat?

In the wild, the hedgehog feeds mainly on insects. It also eats earthworms, snails and slugs, as well as small snakes and frogs. Pet owners feed cat food to hedgehogs that are kept at home by them.
