All-vegetarian Girl Scout troops 68 and 770 know that the way to people's hearts is through their stomachs—so instead of selling cookies outside the local grocery store, they held a "meat-out" and gave away veggie burgers that the store donated for the event. They also shared PETA stickers and leaflets explaining that eating vegetarian food is healthy, tasty, and, best of all, good for animals!

When Larissa Marcich and Sarah Mangold found out that their school was sponsoring a fundraiser for the American Heart Association, which supports cruel animal testing, they started a petition against the event and distributed leaflets explaining why hurting animals is more heartbreaking than heart-saving. The 11-year-olds convinced all but one of their classmates to boycott the fundraiser.

Eleven-year-old Kristin Close was so upset by the abuse she saw at a rodeo that she told a newspaper reporter she was shocked by "how cruel they are to horses and cattle" and wrote a letter to the editor of the newspaper describing the "torture" of a horse who was injured, declaring that she would never go to a rodeo again.

Kyle Jacobs thinks that felines are the cat's meow, so he founded the Hamilton Cat Association and writes its newsletter, Paws for Thought. Kyle has raised money for an animal hospital, rescues stray cats in his neighborhood, and was named "Volunteer of the Year" among local elementary-school students. Me-wow!
