Over at Miss K's place she has a post about a "Big ass pussy," coupled with a picture of an unnaturally big domestic house cat.

That brought to mind the Maine Coon breed, which really is a huge cat.   I still like my Russian Blue, but if I had the room, I'd like to take a chance on a big one like these.   The silver cat is really a looker.  I wonder if you could train them to confront strangers, to be a "watch cat," as it were?
