The cartoon features a band of mice who engage in war against a cat. This is a wartime propaganda film, with the cat symbolizing the Axis powers. A single mouse represents the fifth column, working for the cat and suggesting an appeasement policy.
Plot
Merrie Melodies edition of the short.
The short film begins with a pleasant group of brown mice who are - to the tune of "Ain't We Got Fun" - enjoying various water sports and other fun activities in and around a kitchen sink. Lurking just outside the house is a sinister cat; after he gets inside he gains the confidence of a dim-witted grey mouse who has already underestimated the predator. The cat persuades the easily manipulated rodent - via a promise of cheese, "all you want" - to impress upon the brown mice that he, the cat, is there to save them when, in actuality, he will enslave them.
The grey mouse follows the cat's orders and convinces his compatriots to appease. The brown mice indeed become slaves to the cat, fulfilling his every desire. Finally, he openly states that he wants to eat "a nice, fat, tender mouse". The brown mice flee; the grey mouse runs to join them when the cat turns his appetite toward him. The newly formed brown mouse united alliance prepares for war, constructing a 'secret weapon' to even the upcoming battle: a mechanical bulldog. The ensuing chase forces the cat from the house after being shaved nearly bald. As the brown mice celebrate the victory, the grey mouse tries to claim partial credit (quoting Red Skelton’s line "I Dood it"); in response, he is immediately pied.

The cat is treated as the enemy and symbolizes the Axis Powers. After the cat whispers his plan inside the dim-witted mouse's ear the cat's face briefly mimics that of a stereotypically caricatured Japanese, while Japanese sounding music is briefly heard. When the mouse agrees to fulfill the plan, he gives the cat a Nazi salute. The grey mouse represents the policy of appeasement, and the overall theme of the short is that the policy does not work against the Axis and will lead to ruin. When the cat's fur is shaved off, the first four notes of Ludwig van Beethoven's "Fifth Symphony" are played; these notes were used by the Allied Forces as a symbol for "V" (for "victory") in Morse code; also, when shaved four tufts of hair are left on the cat's back - three short and one long tuft - equivalent to the Morse Code dit-dit-dit-dah - which is the letter "V".
Near the end of the cartoon, the brown mice sing “We did it before and We can do it again”, a patriotic chant that was often used in American films during World War II. The song was co-written in 1941 by Tin Pan Alley songwriter Charles Tobias (who also co-wrote the Merrie Melodies theme some years earlier) as a response to the sneak attack on Pearl Harbor. During the song, a mouse version of the "Buy War Bonds and Stamps" poster can be seen.
