Morris Has a Cold

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 has plans to take a nice long nap in a hammock, but Jerry has gotten there first and is snoozing happily, so the two fight it out to see who gets to sleep there.

Mammy Two-Shoes threatens to throw Tom out of the house if he makes a mess. Jerry sees an opportunity to rid himself of his feline nemesis.

Jerry's eccentric uncle, Pecos, a Texan mouse, comes to spend the night with him before his musical performance on television the next day. He decides to rehearse with his guitar for the performance but each time he plays, one of his guitar strings snaps off. Fortunately, he is able to replace them by plucking off one of Tom's whiskers each time. Tom is rather reluctant about this and tries to hide to protect his whiskers from Uncle Pecos.

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.
