What are rat chips, you ask?

Take one large rat, preferably the size of a cat. Hit it with a car then run it over 30 or 40 times until it's nice and flat. Let it freeze completely and get buried under snow. Then walk Ginger.

We were walking, enjoying the fresh snow, then bam! Her face was in and out of the snow, rat chip clenched in her jaws. We start rolling on the snow, I'm fighting to take my mittens off so I can grab at the rat chip with my bare hands, Ginger's prancing the length of the leash just out of reach. Neighbors with cats are horrified. Neighbors with dogs nod knowingly. I eventually won and got the chip, but what exactly did I win.
