My husband and I have a howler. Not the unhappy kind found in the Harry Potter books (that’s a piece of mail I hope I never receive) but the furry kind that has four paws and whiskers. Leo, half Bengal and half something else, lives to howl — in the bedroom, in the kitchen, in the bathroom. He learned quickly that letting out some howls in the bathtub is awesome because of the reverberation. If I didn’t know better, I’d say he’s half wolf. Is there such a thing as a wolfeline?
