Hey -- I was just thinking about rats. Actually about barking dogs, or rather a city I was in for a while where there were hardly any barking dogs. Eventually I figured out why. It was all the rats. The dogs would go out in the twilight and feast on rats. Well fed dogs don't bark.
Somehow that seems related to San Diego ...
Ummm maybe I should starve my watch pug huh ? lately he sleeps through everything:>)
