Channel 4: The Secret Life of the Zoo
Female Sumatran tiger Kirana faces losing her two sons, who are fully grown and being moved to other zoos to start families of their own. Indonesian dwarf buffalo Oana, one of Chester's most sensitive animals, gives birth - only for the new mum's anxiety to threaten her calf's health. Capuchin monkey Maud's eldest son Rocky is causing problems, refusing to listen to his mother's life lessons, and capybara Lochley has to rely on her mum Lilly to look after her newborn babies when she falls ill.
In this episode, Sarah Beeny meets a young couple who built their first home together on the back of an agricultural trailer for only £25,000, a woman from West Yorkshire who converted three derelict garages for just £12,000, and the creator of an affordable three-bed prefab that can be assembled in a week.
