Pups in Space! Books and Movies

Nearly every generation ship or merchant fleet plying the star-lanes is carrying one or more Ship's Cat. Whether it's the Tree cats from the Planet Sphinx or Tick-Tock from the Telzy Amberdon adventure "Novice" or even Data's cat "spot" from Star Trek the Next Generation, cats are in, as they say, like Flynn.
