Hedgehogs are small, spiny mammals that are found in Europe, Africa, and Asia. They are nocturnal animals and have a diet that consists mostly of insects. Hedgehogs are known for their ability to roll into a ball when they are threatened.
Hedgehogs are relatively small animals, with adults typically measuring between 6 and 12 inches in length. However, there is some variation in size among different hedgehog species. For example, the African hedgehog is the largest species, and can grow up to 18 inches in length.
Hedgehogs grow relatively slowly, with most species taking between six and eight weeks to reach their full adult size. However, African hedgehogs grow more quickly, and can reach their full size in as little as four weeks.
