Noodles was a pet cat that was kept by Ensign Colin Hart at the Starfleet science outpost on the planet Trill.
Biography[]
When Hart was murdered and turned into an unwitting assassin by telepathic clones of the Vess symbiont, his colleague Keisha Rush worried that Noodles would need to be secured and looked after.
After Hart's peers helped Jadzia Dax, Worf and Julian Bashir defeat the Vesses, Rush was happy to report that she had adopted Noodles and he was doing well. (DS9 novel: Revenant)
