Episode 8

Up at the cheetah house, the keepers are hoping romance could be blossoming between Rachel and Lunis. With wild cheetah numbers in steep decline, a successful match between these two could help secure the species' future. But mating behaviour is tricky to spot, so keepers hatch a plan to capture footage of them together at night. As they nervously review the footage, will it reveal the pair growing close, or will hopes of cubs this year be dashed?

Elsewhere, Megan meets Pesto, a tiny five-week-old porcupette. Covered in 30,000 quills and gaining weight fast, he’s already proving to be a big character at Longleat.

Finally, construction is well under way on a bold new project, a state-of-the-art hippo enclosure designed to house four new arrivals. With the clock ticking and plans of future breeding, the pressure is on to get the build completed in time.
