Does a bear s#*t in the woods? You know the famous question. Of course they do, but this could prove it. Watch this cat school a big black bear proving it's not size, it's attitude. 

Who needs a watch dog when you have a kitty cat that will attack a bear! Paco, my Chihuahua is tiny but has big attitude. I swear he thinks he's a German Shepard. It's all about the attitude, just like this fabulous cat. (Faint profanity)
