Kate Humble and Ben Fogle return to Longleat Safari Park. As summer continues, keepers attempt to keep the rhinos cool by encouraging them into a mud bath, but what do you do if a two-ton rhino doesn't want to get in? Two of the world's largest and most lethal species of tarantula arrive at the park, and Jean Johansson attempts to settle a feud between a group of feisty lionesses. All eyes are on the Cheetah Territory drive-through because the two precious cubs are finally going to come face to face with visitors' cars - how will they react, and will the keepers have quick enough reactions to keep the fastest cats on the planet safe from harm?
