In northwest Sydney there’s a magical community space called the Secret Garden. The garden has been running for over 20 years and is staffed almost entirely by volunteers and it’s home to some very special locals including horses, chooks, ducks, and a stubborn curly-horned goat called Cosmo. Dr Harry’s stopping by to help out a hutch of chubby guinea pigs that need a manicure and to meet the rest of the menagerie.
