It's the fifth of seven cartoons starring mischievous mice Hubie and Bertie. The mice arrive at a nice-looking middle-class home which they decide to move into. Unfortunately, when they look inside they see Claude Cat (himself a recurring character), who as the trophies on the stand attest is a champion mouser. Hubie and Bertie have to get Claude out of the house while never letting him know they're there, lest he catch them. The mice then begin a campaign of terror, lowering themselves down the chimney with string, playing an increasingly elaborate set of pranks on Claude in order to frighten him out of the house.
- Bindle Stick: How Hubie and Bertie are carrying their meager belongings when they arrive at the house.
- Big Ball of Violence: Happens when the bulldog attacks Claude, but it's obvious that Claude is getting the worst of it—one time Claude pokes out of the dust cloud with the bulldog's hand around his neck, another time the bulldog pokes out wielding a club, etc.
- Comedic Sociopathy: One of the more sociopathic Warner Brothers cartoons. After all, what we're seeing is two mice invade a cat's home and drive him insane so that they can move in.
- Gaslighting: How the mice drive Claude out. They whack him with sticks, they shove a stick of dynamite under his pillow, they insert a big mean bulldog into the house, all the while taking care that Claude never sees them. The finale is an elaborate prank in which the mice take everything in the living room and nail it to the ceiling, except for the light, which they fix to the floor. Claude wakes up, finds that gravity seems to have turned upside down on him, and finally breaks, fleeing the house in terror.
- Karma Houdini: Hubie and Bertie receive no comeuppance for terrorizing Claude, the cartoon ending with them two of them succeeding in driving him out and taking over the house.
- No More for Me: After an early prank, Claude grabs a stepladder, climbs up to a ceiling light fixture, fishes out a bottle of "Cat Nip", hurls it out the window, and recites a pledge.
- Red Eyes, Take Warning: While we don't see it, we do see the bulldog's vision turn red, which suggest this trope."WHY YOU!" (growing)
- Shout-Out: One of Claude's trophies looks like a cat version of the Academy Award.
