Brother allegedly runs over sis after cat pees on his computer

A cat in Australia apparently figured the best place to relieve itself was on its owner's brother's PC. Not a smart move. The 20-year-old brother completely flipped and threw the cat into his car to take it ... well, who knows where, but it can't be good. His younger sister didn't want to lose her kitty, but big bro was determined and ended up allegedly running over little sis, leaving her with a fractured spine and leg along with a collapsed lung. He's been charged with assault and negligent driving. You know the old saying, "A friend is a brother who was once a bother"? Looks like these two have a long way to go.
