Tweety Bird moves into a city brownstone with his mistress, Granny. A stray Sylvester Cat watches them move in and delights on seeing Tweety. Another of Granny's pets is a bulldog who complicates Sylvester's plan to sneak up close enough to make a grab for Tweety. Sylvester unsuccessfully tries all sorts of disguises, including a moving man, a lamp, a bearskin, and a female dog. He ends up being captured by the dog catcher and placed in the back of a truck surrounded by snarling canines.

Foghorn Leghorn, shivering at the thought of another cold winter in his dilapidated roost, decides to court the well-to-do Miss Prissy, but Prissy won't marry him unless he can prove he'll be a good father to her son, a bespectacled egghead genius who, by scientific means, bests Foghorn in every game they play.

Sylvester has been "blackballed" out of membership to the Loyal Order of Alley Cats Mouse and Chowder Club again. To gain the long-coveted membership, the Grand Master offers to let the lisping puddy tat place a big bell around the neck of the largest mouse he can find, so the cats can pounce on the mouse when they hear the bell. Just as that's going on, Hippety Hopper escapes from a city zoo truck. It's not long before he encounters the hapless Sylvester. Each attempt to place the bell around Hippety's neck ends with Sylvester wearing the bell (and the cats pounding the puddy into submission). In the end, Sylvester finally does get the bell around Hippety's neck, but by the time the cats are ready to pounce on the baby kangaroo-mistaken-for-a-giant-mouse, Hippety has been recaptured. The oblivious cats end up jumping in front of the city zoo truck! Sylvester now gets to serve as Loyal Order's Grand Master.
