A few years ago as my wife was coming downstairs carrying a tray with several glasses 
and stuff tripped over one of our cats. The fall meant lots of broken glass, a frightened  
cat and my wife with severe brusing and 3 broken ribs. My wife claims that the cat tried  
to kill her and still mentions this now and then even though this event happened about  
10 years ago. 
This cat still doesn't like my wife very much but she loves me
