Why isn't jeanne cooper on y and r?

Jeanne Cooper, who played Katherine Chancellor on "The Young and the Restless," passed away on May 8, 2013, at the age of 84. Her character was a significant part of the show's history, but after her death, the writers chose to honor her legacy by writing Katherine out of the storyline rather than recasting the role. Cooper's portrayal of Katherine had a lasting impact on the series, and her absence is still felt by fans and cast members alike.
