I saw this on NBC Nightly News tonight. A young Oregon girl, concerned about the increase of pets in shelters (due to foreclosure) has started a website, FreeKibble. If you click on it and play the trivia question (you do not have to get it right), 20 pieces of Kibble are donated ... so I have a link here and I will send it to all my friends.

This is legitimate, and it will help feed homeless dogs and cats.
