The Animal Rescue site has a link where you can click to donate a bowl of food to a shelter pet. You don't need to sign up and it's free to give.
The site also has daily, heartwarming adoption stories and a store where you can buy items for animals or the people who love them. I've purchased some things for myself as well as gifts for friends.
So, if you have a chance, stop by, click on the link and help a shelter pet!
