I just came across this site via a friend who knows how much I love animals. All you have to do is click on the "click to give" icon and it records your click and the sponsers then make a donation. Naturally they are hoping that you will be lured by the advertising of goods and make a purchase, but you don't have to.
I try to do it everyday, and it is pretty neat to see the statistics for the daily donations. I also like to read the animal success stories. It kinda gives you a warm feeling inside to see that not all people are bad.
