Survival of the Fitest

In my absence, there had been a terrible battle. A battle fought to the bitter end that had tested the skills of both combatants to the utmost. I could imagine the scene as it played out across my apartment. The one running as though its life depended on it and the other waiting, watching and calculating. The fight had been relatively quick as there was almost no evidence to attest to its occurrence. There was an unexplained stain, some mystery dirt and that was all. If it hadn't been for the corpse, no one would have been any the wiser. But there was a corpse and I found it, stiff as a board. My cat has earned her first mousing badge.
