A Wonderful Friendship. Tomcat Konrad's whiskers are standing on end: his sandwich just talked to him! His ever-worried mother has once again meant particularly well for him and sent Konrad off with a hefty oat-fed mouse - but she's not dead at all; she's very much alive! Moreover, her name is Marie-Antoinette, and she turns out to be quite affectionate. Before he knows it, Tomcat Konrad has taken a liking to the cheeky little mouse. How embarrassing! Thus begins a grand adventure full of humor and situational comedy - during which Tomcat Konrad not only gets to know himself and the world better but also makes friends for life!.
