Katherine Schwarzenegger Pratt’s latest children’s book Kat and Brandy will be released on November 4, 2025, and is aimed at children aged 3 to 7 years.
The story is inspired by Katherine’s real-life childhood pony, Brandy, and her own experience of overcoming fear after falling off a horse.
The book features artwork by illustrator Petra Brown and focuses on themes of bravery, confidence, and the healing bond between humans and animals.
Katherine credits her husband Chris Pratt, mother Maria Shriver, and her close-knit family—including her father Arnold Schwarzenegger—for keeping her grounded and confident as a mom.
She practices Transcendental Meditation (TM) to stay present and manage parenting stress, and she uses her platform to promote positive, family-friendly messages through her writing and public work.
