A hedgehog is a small, spiny mammal that belongs to the Erinaceidae family. They are found in parts of Europe, Asia, and Africa.
Hedgehogs are omnivores and their diet consists of insects, worms, snails, fruits, and plants. They are also known to eat small rodents and birds.
Hedgehogs can make good pets for some people, but they require a lot of care and attention. They also have specific dietary needs and can be quite expensive to care for properly.
The spines on a hedgehog are made of keratin, the same material that makes up human hair and nails. They are not poisonous or barbed, but are used as a defense mechanism.
When threatened, hedgehogs will curl into a tight ball, exposing only their spines for protection. They may also make a hissing or clicking noise to scare away predators. In some cases, they may release a foul-smelling odor from their anal glands as a defense mechanism.
