Momma cat is teaching her kittens to catch mice. Meanwhile, across the basement, Momma mouse is teaching her little ones how to avoid cats. One of each of the kids sneaks out; they meet in the middle. After a brief staring match, the mouse kicks the kitten's fanny (literally); the kitten runs to momma, who complains to Mrs. Mouse to no real avail. The mouse invites the kitten back to dance to the wind-up record player. The kitten falls into a drain, and the mouse dives after it, while both mothers fret. The rescue involves the mouse using a guitar as a boat, then grabbing a board stretched across a hole; the kitten grabs on, a whirlpool twists both of them, and as they untwist, the board helicopters them out of the hole. The mothers are happy, and all the kids play together, until Mrs. Cat remembers that Mrs. Mouse poked her in the eyes on their first meeting; everyone starts fighting.
