Officially,
 there hasn't been a documented mountain lion sighting in this part of 
Canada since the late 1930s, but many people still swear they've seen or
 heard the big cats in the woods of New Brunswick. 
Researcher
 Bill Betty doesn't think they're all mistaken....he's with the Eastern 
Puma Research Network and he tells Tide News there's an even stranger 
possibility than a new and unknown species...wild house cats, which have
 been documented to get as big as 56 inches after living outside for 
generations.
He says 
the big black cats people have reported seeing could be the Asiatic 
Leopard which are a problem in Europe but haven't been proven to exist 
yet here, but we'll just have to wait until one is captured to know for 
sure.
