Image 2. Aggie & Sarah introduction slowly started. As Aggie is blind we don’t want to stress her too much, so we progressively increase the time they spend together. So far so good, they are not friends yet but they manage to cohabite well during the short time together. Image 3. In the Mandrill enclosure, we always close a small section to grow some natural plants. When the plants are big enough we open to the mandrill so they can forage as they will do in the wild.
