A toddler was lightly injured by a wolf at a Pennsylvania theme park zoo after he crawled under a fence and stuck his hand into the animal’s enclosure. The child was never inside the wolf habitat at the ZooAmerica North American Wildlife Park, which is part of the Hersheypark theme park.

After the “unsupervised” child reached the metal enclosure around the wolf habitat on Saturday morning and put his hand through, a wolf approached “and made contact with the child’s hand,” according to a statement from the zoo. “This type of response is consistent with natural animal behaviour, and was not a sign of aggression,” the zoo said in a statement.
