Jones (Alien)

Jones is a cat who is featured in both Alien and Aliens.

Jones, nicknamed "Jonesy", is an American Shorthair who is the rodent-control ship's cat on the Nostromo. After the birth and escape of the Alien, Jones is detected by the crew and risks interfering with the ship's motion sensors (which could mistake the cat's movements for those of the Alien).

Samuel Brett finds Jones in the cargo room, where the Alien kills Brett as Jones watches. When the remaining crew members prepare to escape the ship, Ellen Ripley loads Jones into a pet carrier but must temporarily abandon him as the Alien approaches her. The Alien inspects Jones but leaves him alone, since the cat poses no threat.

Ripley retrieves Jones and flees with him on a shuttle. She and the cat are in cryosleep for fifty-seven years, until they are rescued. Jones remains Ripley's pet for the duration of her new employment until she departs on the Sulaco, leaving him behind.
