An alley cat is foraging for food when he sees Tom's house and decides it's a rich haul. He dresses as a foundling baby and lands on the doorstep. Tom takes him in and Butch proceeds to raid the fridge between Tom's babying him. What he doesn't know is that Jerry's going to grab the ham Butch swiped every chance he gets.
Nobody's home, so Tom invites his alley cat friends in to look at home movies (clips from earlier cartoons where Tom gets the drop on Spike). While they're showing them, Spike sneaks in.
Jerry's little duckling friend has packed his bag and is all set to fly south for the winter despite the book Jerry keeps showing him that points out that domestic ducks do not fly south, and despite his inability to fly at all.
