Help Shelter Pets for FREE by Playing Trivia! Experience Project

I ran across this cool social networking site called Experience Project. I haven't explored the site itself too much, but I did see this: You can play trivia, and for each correct answer, the Experience Project will donate the equivalent of one kibble of cat or dog food to the Rocket Dog Rescue and the Urban Cat Project.

You don't have to register to play, but registering will let you access the other features of the site, and helps you earn bonuses. Check it out -- have fun playing trivia, and help shelter pets at the same time, for FREE!
