Cat-Tastrophy

Tom's chasing Jerry when he runs right into a sleeping dog and the two of them must work together to fend him off.

Tom subjects Jerry to his usual harassment; but the cat finds a new enemy, and the mouse finds a new friend, in the canary of the house.

Donald Duck tries to exhibit his golfing ability to his nephews only to have them tease him with sneezes, noises and "trick" clubs. Finally, they put a grasshopper in a ball and it "jumps" all over.

Mammy Two-Shoes replaces Tom with a younger cat who is a lightning-quick mouser. Tom and Jerry form an alliance in order to get rid of this dangerous newcomer.

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.
