Animals on Call. Fifteen-year-old Maddy depends on a machine to keep her alive. She has spent the past two years in hospital and is tired of being "different", but something can help and it's not a drug. It's a menagerie of "therapy animals", including a tiger cub. Narrated by Rolf Harris. See today's choices. Producer Vanessa Berlowitz
