This is a Binturong or "bear cat" though it is the largest member of the civet family, not a bear nor cat.
These are mostly nocturnal and the tour group I was with found this one the night before
eating from a fruiting fig tree. We went back the next morning for better pics but a large male orangutan
had taken over the fig tree. Fortunately, we found this Binturong sleeping 2 trees over.
