Beaver is hiding a cat in his room, the cat which was sitting outside on the porch when he got home. When June speaks on the phone to a neighbor named Mrs. Prentiss, who is missing her cat Bootsie, Ward puts two and two together and figures that Beaver's strange behavior means he has the cat. Mrs. Prentiss is glad to come and pick it up, but after she leaves, Beaver learns that he shouldn't have fed it as it now knows their house is a place where it can get food. Indeed, Bootsie comes back in the middle of the night, meowing for food, and Beaver takes it back the next day to Mrs. Prentiss. But that doesn't stop it from coming back yet again. The Cleavers figure they have to come up with an ingenious way to keep Bootsie away, but their plan has its own unintended consequence.
