Ever hear of a Cat attacking a Pit Bull?

Although most new stories involve pit bulls attacking people or animals, my son tells me that pit bulls are gentle if trained that way. He has a very sweet pit bull, and my daughter had a very sweet chow. Still, I'm a little cautious around pit bulls and chows. What do you think?

Check out this story of a cat attacking a sweet pit bull:
