5. Episode 5

It’s an anxious time for Alison and the primate care staff, as chimp Jestah goes under the knife following a diagnosis of mouth cancer. Wildlife vet John Lewis and local vet Dave Harding team up to carry out the complicated operation, to remove the tumour and reconstruct Jestah’s lower lip. Woolly monkey, Pacaja has had a baby and both are doing well. She is an experienced and confident mum so the team are happy for her to take her new born into the large outside pond enclosure. An enormous felled tree helps the guenon family of four scale new heights. While marmosets, Ruby, Oscar, and their family of four youngsters, are given a lively breakfast and the nursery orang-utans have a ball with a colourful treat.
