ENRICHMENT FOR LUTUNG
To enter the Lutung cage, you must be brave, because they are naturally temperamental. They would bite and scratch you if they feel threatened by you. But they are not as smart as the orangutans.
Enrichment idea is to put a swing made of second car tire so Lutung got a toy to play. We think, he loves it. (Inggrid Christy, Orangufriends Samarinda)
