It's time to deck the halls because Ben Fogle and Kate Humble are heading back to Longleat Safari Park for a magical week of programmes.

Harry the lion has a problem that could ruin his Christmas - he has broken one of his enormous canine teeth. The keepers have called in renowned dentist Peter Emily, whose plan is to perform root canal work on Harry, but to get close to his lethal jaws, they first need to knock Harry out with a sedative. Once he is asleep, the team can get to work, but just as the operation starts, Harry stops breathing, leaving everyone hoping for a Christmas miracle.

Christmas can cause the occasional family rift, and it's no different down at the meerkat enclosure. Hailing from the Kalahari desert, meerkats live in matriarchal societies, so the ladies are in charge, and the keepers suspect a change at the top – 12-year-old Cassie may have been usurped by her daughter Harley. A group of meerkats is known as a mob and that's exactly what they have turned into with all the infighting, so the keepers have called in wildlife cameraman Hamza Yassin to see if there has indeed been a power shift.

The keepers have everything crossed for a white Christmas because animals such as the red pandas and Amur tigers have special adaptations to thrive in snowy conditions. While they wait to see if the park will become a magical winter wonderland this year, Lord and Lady Bath reminisce about past years when snow fell at the park.

Megan McCubbin is on hand to deliver presents and treats to animals that originate from all over the world, so what will they make of our British Christmas traditions? Will the anteaters from South America manage to break into a Christmas cracker, and what does an Australian wallaby make of a brussels sprout?

It wouldn't be Christmas without mistletoe and a hint of romance, and that's exactly what the keepers are hoping for at the cheetah enclosure. Rachael is the stunning female looking for a mate, and she has two boys to choose from, brothers Mo and Bolt. A litter of cheetah cubs would make everyone's Christmases come at once because they are classed as vulnerable in the wild. However, Rachael doesn't appear to be particularly interested in either of the boys, so cameraman Hamza Yassin trains his lens on them to find out why.

Deciding what to eat on the big day is always a big decision, and the estate has records of what's been on the winter menu as far back as 1603, with prunes, raisins and peppercorns all on the list. Ben discovers that by the 19th century, things were getting a bit more extensive, with a turkey dinner for lunch and then a seven-course meal in the evening!

Rather than serving Christmas dinner on a plate, for the hyenas Megan McCubbin has a different approach entirely. She and the keepers are adding lumps of meat to a Christmas tree in order to create a brilliant enrichment puzzle for them. The moment the keepers release Akuma and Nkuru, they begin to hunt as a team, finding the treats buried in the tree. But as their senses are heightened, how long with it be before these great African scavengers destroy the festive display?
