if you had a kitten and a puppy from birth,both born the same week and both raised by you, now avance to five years from now and late at night, a thief enters your home with certain ill intent.
The dog will fight to the death to defend you and the cat will sneak out an opening in the house with the video cam and go to an outside window,film the whole thing,sell it to CNN and retire.
sounds like a Paris Hilton documentaty huh
A few years ago I read a news item about a cat in England who was stealing stuff from other people's houses via the cat doors. He brought home all kinds of stuff, including IIRC an umbrella and a golf club.
