He joined these three men, together with René Meulenbroek and Diederick van Kleef, in the creation of the amateur comic magazine De Omelet. Seven issues were published between 1976 and 1978. Whereas the others moved on to found Studio Arnhem and become professional comic artists and illustrators, the comic careers of Catz and Van Kleef ended here.
