On her degree course at Falmouth School of Art, Catherine met her husband, the artist and writer, Laurence Anholt. Together they moved to London, to take Master's Degrees at the Royal College of Art and the Royal Academy respectively.
Over the next 30 years, the Anholts produced more than 200 children's books, which have been translated into 30 languages. Their titles have won numerous awards including the Nestlé Smarties Gold Award on two occasions.
