[1] It is a sequel to 1942's A Tale of Two Kitties, with the Abbott and Costello characterizations ("Babbit and Catstello") now cast as mice.

Catstello is being chased by a cat rapidly at high speed around the house, yelling "Hey Babbit!"

Their schemes include creeping past a sleeping cat, which doesn't go so well as Catstello runs off at first time, a small airplane and a rope and pulley system.

Finally, Catstello manages to escape the cat with a wedge of Swiss cheese, which unfortunately Babbit doesn't like.

Fed-up with Babbit constantly ordering him around and repetitively slapping him as well as his ingratitude for all of Catsello's efforts, Catstello continuously slaps him and force-feeds Babbit chunks of Swiss cheese, remarking "Ooohhh, I'm a baaaaaaad boy!"
