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.
