It is legal to buy a hedgehog in most states; however, certain locations have laws barring hedgehog purchases and ownership, according to National Journal. Hedgehogs are illegal to buy in Hawaii, Pennsylvania, Georgia, Maine and California, as well as Washington, D.C. and New York City's boroughs.
There are some exceptions to the laws; for example, people in Arizona are allowed to keep hedgehogs as pets with an approved permit, explains azcentral.com. However, few applications are approved. California also issues hedgehog permits, but permits are approved only for educational purposes, not for pet hedgehogs, according to the California Department of Fish and Wildlife. In Pennsylvania, it is not legal to purchase hedgehogs, but the animals can be adopted from another state, states Point Park News Service.
