and also:
The Luwak (Paradoxurus hermaphroditus) denizen of the coffee (kopi) plantations of Java, Sumatra, and Sulawesi, eats only the ripest coffee cherries.
Unable to digest the coffee beans the Luwak graciously deposits them on the jungle floor where they are eagerly collected by the locals.
The stomach acids and enzymatic action involved in this unique fermentation process produces the beans for the world’s rarest coffee beverage.

Common Palm Civet
(Paradoxurus hermaphroditus)
Range and Habitat
The common palm civet is found in the temperate and tropical rainforests from Kashmir in the west to the Philippines, from China in the north to the Sundas islands.
Physical Appearance
The common palm civet has coarse, shaggy hair that is usually a greyish color, with black on its feet, ears and muzzle. It has three rows of black markings on its body. The markings on its face resemble a raccoon's. It's tail does not have rings, unlike similar palm civet species. Their body is stocky and long. Its species name comes from the fact that both sexes have scent glands underneath their tail that resemble testicles. They can spray a noxious secretion from this gland.
Diet
The common palm civet is primarily frugivorous, but is omnivorous. It feeds mostly on berries, fleshy fruits, and the fruit of Ficus trees. It is picky about the fruit that it eats, picking only ripe fruit. It will also eat birds, rodents and insects as well as fruit.
Reproduction and Social Behavior
The common palm civet is solitary, nocturnal, and arboreal. They spend the day asleep in a tree hollow. They are territorial. Young are born in tree hollows or in boulder crevices.
Threats
It is pursued by humans, who kil them for damaging orchards and plantations. Its feces are used in coffee made in Indonesia. The name Toddy cat comes from the name for wine that comes from the sap of the palm tree: toddy. The palm civet feeds on this sap.
Subspecies
Not much information is given on subspecies. However, one subspecies, the Mentawai palm civet (Paradoxurus hermaphroditus lignicolor ), found in the Indonesian island of Sumatra, is listed as Vulnerable by the IUCN.
