Kiddin' the Kitten

A lazy and fat cat, named Dodsworth, is ordered by his mistress to catch mice that have invaded her home and are terrorizing her. Dodsworth doesn't want to condescend to personal physical effort to catch the mice, so dons a professor's hat and dupes a kitten into doing the job for him, on the pretext that he's a teacher who is giving the kitten a valuable learning experience.
