After taking a director's suggestion to visit an animal shelter for a film role, teen actor Lou Wegner was shocked at the number of pets who are euthanized because they don’t have homes.

So, at age 14, the Ohio native started Kids Against Animal Cruelty. Two years later, the group is one of the fastest-growing animal rescues in the country, using social networking to help save the lives of 20,000 pets at high-kill shelters.

Wegner, who recently finished a pilot for The Thundermans on Nickelodeon and sings in the pop band Blonde, hopes to open a chapter of his group in every state.

“The bigger the group you work with, the bigger difference you can make," he said.
