hmm when a cat turns on her back with here paws waving in the air, she/he's saying "back the the "f"word off!" or I'll scratch you bad. Even when they are playing the behave that way to show their claws etc...
When a dog does that he surrenders.
Thats why cat-dog fights are so funneh <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
