In spite of what has been said and shown on the URL about cougars, there have been sightings of some form of cougar-type cat along the northern borders of NH, VT, and much of northern Maine. Like any sightings the sighters didn't happen to have a camera with them, or the film was a bit dodgy so the result was an amorphous something that might have been a cougar or panther, so we have no hard evidence. Much of this region is fairly rugged country with few people so you don't get complaints of Fluffy or Wooffums going missing - which could also be the result of an encounter with a coyote, bobcat, lynx, or even fisher - large animal of the weasle family - half way between a weasle and a wolverine, but climbs trees readily.

Panthers or mountain lions were common in NH and VT as late as the 19th century, so there is little reason to believe that they might not be coming back.
