Sumatran tiger cubs are some of the most critically endangered in the world so Giles took two – Spot and Stripe – home with him when they were born at Australia Zoo in Queensland, to give them round the clock care for the first four months of their lives.
Growing up in a suburban home where they are completely reliant on their foster dad brings trials and tribulations for Spot and Stripe, but also a real hope for the future of their species.
It's the toughest parenting job of Giles's life, but will this method save them from extinction in the wild?
