One of my cats (Cream Puff - a big, neutered and declawed (which I wouldn't do again) male who tried very hard not to live up to his name) used to look down out of the window of my second-floor apartment at the geese across the street with this look in his eye that said "I could get me one of those."

I don't know what would have happened if he ever got out and near one - probably not much since he usually ended up hiding as soon as he got out.
