Graham knocks her out and takes her to the health centre for examination and treatment. Now Graham and the keepers have to decide whether to do a hysterectomy on the old bear. Baby Lion Move Two young lions are about to experience their exhibit for the first time. They are nine months old, but most of their exhibit was closed for the winter so they haven't had the opportunity to experience it. Today is the day Linda will let them in. Panda Training Last season Louisa was the head keeper in elephants. She has been moved to the health centre and has become the zoo's chief animal trainer. Today she is training Chao Nao a red panda who has been very sick in the past. Chao needs regular examinations and the vets do not want to anaesthetize her every time. So it is Louisa's job to train Chao to accept being examined while she is awake.
