When Sir Reginald Mouse disappears from his apartment, the neighbors in the building advertise his room for rent. One prospective renter after another comes to see the apartment but finds fault with one or another of the neighbors. The hardworking Ant finds the Hen lazy, the Rabbit criticizes the Cuckoo for abandoning her young, the Pig finds the Cat beneath him because of her color (and is roundly chased out by the neighbors for his racism), and the Nightingale thinks the Squirrel just a noisemaker. At last the Dove arrives, bringing with her an eye for the good and restoring an atmosphere of peace
