Hedgehog
Hedgehogs are cute little harmless critters that can be kept as pets even if several cities and States around the US consider them as wild animals and thus illegal. However, they actually make excellent pets because they pose no threat even if they look like they can prick you many times over with their 5,000 to 7,000 quills. Hedgehogs are collectively known as an “array,” though they prefer to be alone most of the time.
