Visit Click to Feed - Big Cat Rescue everyday and click on the cookie to help feed big cats. It's easy and only takes a minute of your time and it's absolutely free to you! They also have a lot of big cat videos to watch! Care2 usually removes my petitions when I share information about other sites, so make sure you save the link.
