The episode in which Miss Kitty departs from Gunsmoke is titled "The Sharecroppers," and it aired on March 9, 1974. In this episode, Miss Kitty reveals that she has received a letter from her aunt in England, who has fallen ill. She decides to sell the Long Branch Saloon and return to England to care for her aunt. Miss Kitty's departure is a bittersweet moment, as she says goodbye to her friends and the town she has called home for many years. Interestingly, Miss Kitty's death is addressed in a later Gunsmoke movie, titled "Gunsmoke: To the Last Man," which was released in 1992. This movie is set 25 years after the end of the original series and features many of the original cast members, including James Arness as Marshal Dillon. In this movie, it is revealed that Miss Kitty passed away several years earlier from cancer.

Nonetheless, it provides an explanation for Miss Kitty's absence and ultimate fate, albeit one that is not officially recognized by the show's creators or fans. In conclusion, Miss Kitty, the beloved proprietress of the Long Branch Saloon on Gunsmoke, did not die during the original run of the series. Amanda Blake, the actress who portrayed Miss Kitty, left the show in 1974 to pursue other opportunities. While Miss Kitty's death is addressed in the 1992 Gunsmoke movie "To the Last Man," these events are not considered canonical and should be viewed as a separate, non-canon storyline.
