A baby hedgehog is called a hoglet. This name has been in use since the early 1990s. They are sometimes called hedgehoglets. Before the 1990s, hedgehog babies were referred to as pups, urchins, kits or piglets. The term urchin is also popular today.

Baby hedgehogs are in the womb for 35 days, and they are born with their first spines, which are white and covered by a layer of skin. The spines start to emerge through the skin as soon as the hoglets are born.
