Amur - or Siberian - tigers are an endangered subspecies, with only around 500 left in the wild. Knowsley's two Amur tigers, Miron and Sinda, need to mate, so the keepers try anew, mindful that previous attempted matings between the two have not gone well. In a fight for supremacy in the Knowsley wolf pack, young Maya is losing. Thankfully, the keepers have a plan to offer help. The 200-strong baboon troop fight a lot and illness is a weakness. Twiggy needs antibiotics, so it is important the other baboons cannot view this action, or they might attack.
