Mugsy and Stump are two extraordinary cats whose owners will not let them into a certain room, where they previously had full access. Stump, glimpsing a wrapped bundle in the room, believes the humans have a surprise present for them, and goes to great lengths to find out what it is. Mugsy, already knows that the “bundle” is a new baby, and he grows quite tired of Stump’s relentless pursuit of the “present” fantasy.
In the end, the cats meet the baby, and Stump is forced to admit to Mugsy that he might have been wrong. When he inspects the baby, however, he maintains his belief that the humans have given the cats the best present possible.
