Afaik they are naturaly suposed to eat fruits and leaves off of trees .. but I would Imaging most of the trees are chopped down now where they would live in the wild and alot are brought out of there natural habitat for pets and other reasons. One thing I saw was about this orang-utan that had seen it’s mother killed for some stupid reason, I think to protect crops or something and had been locked up in this tiny cage for ages. The poor thing had pretty much gone a bit mental in there and had to be rehabilitated after being rescued. Orang-utan’s are one of the most emotional of the primates and apart from humans the mothers stay with there kids the longest, up untill mid to late teens iirc! This one was only a year or two old.
