Flyball was the only cat on the Moon. He had gone there with his friend Colonel Fred Stone—and now a new rocket ship was being built to take Colonel Stone, and of course Flyball, to the planet Venus.

Flyball's mind was busy. What would a Space Cat find on Venus? Mice? There had been none on the Moon. Birds, perhaps?

The things he did find were a great surprise even to a Space Cat.

The story is told with the same delightful humor as the first book about Space Cat, and is again illustrated by Paul Galdone, who first pictured Flyball's jaunty personality.
