Excitement is mounting at the park as keepers have noticed young Amur tigers Red and Yana appear to be in the mood for love. As Kate Humble and Ben Fogle discover, everyone’s got their fingers crossed that this burgeoning romance might just herald the arrival of cubs – the park's first tiger babies for nearly 20 years, and especially important as Amurs are so endangered in the wild.

But are these tigers too young for parenthood, and is everyone reading too much into possible signs of pregnancy? In the hope that Yana is about to be a mum, Kate helps prepare a maternity unit at the Tiger House.

A rare little Hyrax is in trouble. Can Tadallah, which means feisty one, live up to her name? Related to the elephant and the only breeding female, has she got what it takes to survive investigative tests?

In the East Africa Safari, a trio of newcomers has just arrived. Three one-year-old ostriches will help with the breeding programme - as long as they are, as hoped, all girls. Jean Johansson helps collects feathers for DNA tests and reveals the results. What will happen if there’s a boy in the mix?

The fearsome Cuban crocs are settling in nicely, but looking after a new species, especially these giant reptilians, is challenging for keepers. Kate helps with thermal imaging to see if Fang and Keo have got everything they need in Crocodile Creek to be in tip-top condition. Is their new home as des-res as it should be?

And climb aboard to see how Capt Jean copes when she takes over the tiller and the tour on one of Half Mile Lake’s boats. Beware the hippos… Show less
