Your enthusiasm for yesterday's Puppy armada led to many nice emails -- and more than a few submissions, suggesting that there is, quite possibly, a whole world of adorable cat vs. dog videos out there. If you have one, by all means, send it in! Note: They all don't have to be as "artfully" crafted as the one below. (And thanks to Jennifer Godwin for the heads-up.) And yes, we already have one of these lined up for tomorrow, too. So come back -- and spread the word!
