A Street Cat Named Sylvester (1953)

The title of this cartoon is a misnomer, because it is in fact Tweety Bird who is the homeless one here, and Sylvester is Granny's pet. Tweety seeks shelter from a blizzard and taps on Granny's house door. Sylvester answers and grabs the canary. He tries to hide Tweety from Granny while evading the attacks of Hector, Granny's bed-ridden bulldog, who wants revenge on Sylvester for his broken leg. Tweety keeps escaping Sylvester's clutches, with Hector's help.
