Father Knows Best star Lauren Chapin, best known as Kathy “Kitten” Anderson, has passed away at age 80. Her son, Matthew Chapin, announced on February 25, 2026, that she died after battling illness for five years, later confirming it was cancer.
Chapin rose to fame at just six years old after being chosen from 250 girls for her breakout role. She fondly remembered co-star Robert Young as a father figure. However, early stardom brought struggles, and she later faced addiction and legal troubles, becoming outspoken about the hardships child actors endure.
Beyond her iconic sitcom role, she appeared in TV shows and films and reprised her character in reunion specials. Later in life, Chapin devoted herself to faith, ministry, and helping others overcome addiction. She became an author, speaker, and ordained evangelist, sharing her recovery story publicly and supporting charitable causes.
She is remembered not only for her childhood fame, but for her perseverance, honesty, and dedication to helping others.
