Her family added:

“She loved her animals and she was steadfast in her support of the unhoused community, so any donations in her memory to a local food bank or an animal shelter would be a wonderful and much appreciated tribute to her.”

Keaton was a passionate animal lover, often seen advocating for animal shelters and rescue organizations. She used her platform not just to entertain millions, but also to inspire compassion and give back to those in need.
