An Animagus, obviously. Probably unegistered, but we'll never know since our Department of Magic operates on the same secrecy rules as Britain's Ministry.

I think the forest is reclaiming the city sometimes. I haven't seen a fox, but there's a pack (is that the word?) of oppossums in my neighborhood and raccoons in the sewers. And the southern suburbs are full of deer.
Foxes are kinda creepy, aren't they?

Well, aren't there rumors of a big cat that roams the suburbs terrorizing neighborhood pets? (Which, in my opinion, is a really weird rumor.)

Dude, in the story I heard it was Golden Valley. Right by the Humane Society!
