A young Arctic fox found running loose in Michigan is now at home at the Buffalo Zoo.

The zoo estimates the male fox named Ash is about 2 years old. He was wearing a harness when he was found in Ann Arbor, leading authorities to believe the animal was someone's pet.

Michigan's Humane Society of Huron Valley donated Ash to the Buffalo Zoo, which recently opened the Arctic Edge exhibit the fox and another will eventually inhabit.

Zoo officials say Ash's past involvement with humans would make it difficult to release him into the wild.
