Hiding his condition became too much of a burden for Katz and he eventually disclosed it. He began speaking publicly as part of a tour sponsored by a manufacturer of medications used to treat MS."People have been pretty supportive; nobody ever had me in mind for an action film because of the kind of work I do -- mostly in the world of animation, which is not a big issue because as a person, I can't run that fast; as a cartoon character, I can fly -- literally." Katz, who now gets around with the help of a motorized scooter and performs onstage with the aid of a cane, says he doesn't regret his decision: "One of the reasons I disclosed my condition is because it is much easier to live with MS than to pretend you don't have it. If I could convince everyone of that, my job here is done."
