Cat and Mouse, published in Germany in 1961 as Katz und Maus, is a novella by Günter Grass, the second book of the Danzig Trilogy, and the sequel to The Tin Drum. It is about Joachim Mahlke, an alienated only child without a father. The narrator Pilenz "alone could be termed his friend, if it were possible to be friends with Mahlke" (p. 78); much of Pilenz's narration addresses Mahlke directly by means of second-person narration. The story is set in Danzig (Gdańsk) around the time of the Second World War and Nazi rule.
