Being on a plane for hours can feel like being inside a cage. So it’s not too surprising that a 40-pound male wolverine named Kasper chewed through his metal cage at Newark International Airport Tuesday.

The New York Times reports that the animal flew in from Norway’s Kristiansand Zoo and was passing through Newark to go through U.S. customs and connect flights en route to the Alaska Wildlife Conservation Center.

While the animal did not actually escape (phew!), its growling did spook a representative from the wildlife conservation center, the Times reports.

But after all that fuss, when the Bronx Zoo provided a new cage, the wolverine did not want to make the switch, and had to be tranquilized for the transfer to happen.
