The underground comic by Robert Crumb that introduced Fritz the Cat is titled Fritz the Cat.
Fritz the Cat is an anthropomorphic character created by Robert Crumb in the 1960s. The stories appeared in underground comics and student publications before the character became one of Crumb’s best-known creations.
Fritz is portrayed as a self-centered, sexually adventurous cat whose stories satirize popular culture, politics, and countercultural attitudes. The character’s adult subject matter helped distinguish underground comix from conventional newspaper strips and mainstream superhero comics.
An animated film titled Fritz the Cat was released in 1972, directed by Ralph Bakshi. It was based on Crumb’s character but was not written or directed by Crumb, and Crumb strongly disliked the film’s treatment of his creation.
