    DR. DREW

    Cause: Spay/Neuter Advocacy

    How He Got Involved: It wasn't hard for Dr. Drew to sign on as one of PETA's spokespeople in August. A proud owner of two dogs, Daisy and Lulu, Dr. Drew Pinsky understands the importance of spaying and neutering companion pets. "[There are] eight million homeless pets in this country, four million — only half of them ever get adopted. If we are responsible enough to adopt a pet, we've got to be responsible enough to get them spayed or neutered."
