A staunch animal rights supporter, Kari Kennell Whitman protested the Annual Hot Dog Lunch on Capitol Hill, on Wednesday, July 21, 2004. Representing PETA, and wearing plastic lettuce-leaf bikinis, Kari Kennell and fellow Playboy Playmate Lauren Anderson (Miss July 2002) sold vegetable hot dogs to members of Congress outside the Rayburn Office Building in Washington D.C. The courtyard inside the building was the location for the 2004 Hot Dog Lunch, which was sponsored by the American Meat Institute and the National Hot Dog and Sausage Council. The annual luncheon is a celebration of "National Hot Dog Month", which is the month of July.
In May 2006, Kari Kennell Whitman was given her own reality television show on the WE (Women's Entertainment) Television Network. The series was titled "Designer To The Stars: Kari Whitman" and featured Whitman redesigning rooms within celebrity homes. The series aired in March 2007.
