Man Attacks Bob-Cat with Samurai Sword to Save Dog

Who has a samurai sword in their garage, better yet who uses a samurai sword they have in their garage?  Apparently its time for me to get one though.  I still feel like a pitbull could take down a mountain lion.  If I was this "hero" I would have SPRINTED back to my house locked the doors, and said if the dog makes it back he makes it back.
