it's www.experienceproject.com/savecats it's a trivia game and for every correct answer they donate kibbles of food to shelter cats, i'm addicted to it.
I was going to post a thread for that site when I got home today
I've "accumulated" 300-400 kibble so far.
Also, if anyone has a myspace, you can add the "SaveCats" application, and it will put a link to that site on their page and a picture of a shelter cat.
