History:
(West Coast Avengers III#5) - As the West Coast Avengers were defeating the car-levitating Gridlock, Gwenpool noticed a small gray cat inside one of the cars that Gridlock had been levitating. Rushing to rescue the kitty from the now-falling car, Gwenpool jumped toward the car and Kid Omega telekinetically disassembled the car to give Gwenpool better access to its insides. Gwenpool successfully saved the cat and Kid Omega made sure the other falling cars did not hit either Gwenpool or the cat. The team then returned to their headquarters, where Gwenpool announced plans to name the cat Jeff.

(West Coast Avengers III#7 (fb) - BTS) - Hawkeye (Kate Bishop) ultimately made Gwenpool give back the kitten.

Comments: Created by Kelly Thompson and Daniele Di Nicuolo.

    Jeff is not mentioned by name in West Coast Avengers III#7 but Kate Bishop mentions having made Gwenpool give back the kitten she took. The only kitten we'd seen Gwenpool acquire at that point was the cat Jeff so one can make the logical assumption that Kate made Gwenpool return Jeff to its proper owner.
