Liz Bonnin takes us inside the dramatic world of big animal surgery. This time, she travels to a sanctuary in South Africa to witness an extraordinary operation inside the jaws of Ricci, a nine-year-old rescued lion. Ricci has problems with his teeth so severe they are preventing him from feeding. It takes one of the world’s leading vets using an array of specially-made tools to fix them. But the story takes a dangerous twist as Ricci begins to wake up from the anaesthetic mid-surgery.
