The quadruped on the left is Panther, who played the unimaginatively-named "Cat" on "Early Edition" for four years. The biped on the right is Vik Rubenfeld, one of the show's three co-creators. This picture was taken at the 2001 "Early Edition" Convention in Chicago.
Vik and I were also able to pose uncomfortably with Shanesia Davis-Williams, one of the human stars of the show, who in this picture seems to be pretending she's somewhere else. In fact, I think she's clicking her heels together three times and trying to get back to Kansas.
