Catalyst

Pilot, engineer, doctor--ship's cat? Since the early days of interstellar travel, the so-called Barque Cats have become essential to the well-staffed space vessel. Assisted by humans--Cat Persons--with whom they share a deep and loving bond, the Barque Cats are responsible for keeping spacecraft free of vermin, for alerting crews to environmental hazards, and for acting as morale officers.
But a widespread epidemic affecting livestock on numerous planets throws the felines' future into doubt. Suddenly the galactic government announces a plan to impound and possibly destroy all exposed animals, including the Barque Cats. With the clock racing against them, a handful of very special kittens and their humans will join forces to save the Barque Cats, and quite possibly the universe as they know it, from total destruction.
