KOPI LUWAK: The Indonesian palm civet prowls about the coffee plantation, eats choice coffee beans, and excretes them, undigested. The resulting coffee beans, which pass through within millimeters of the cat's perineal glands, are gathered and brewed into coffee. It is reported to be the most expensive coffee in the world. [In other words, it's civet bunghole-flavored coffee.] Here's a pic of a civet:
Some more info about "Kopi Luwak" (a.k.a. civet bunghole-flavored coffee): According to local legend, the palm civet, in spite of its categorization as an omnivore, is a fastidiously picky eater. Thus, it is thought that this musky epicure selects only the coffee cherries that are at their very peak of ripeness and savor. (Other foodstuffs selected by the civet at their very peak of ripeness and savor include: insects, palm sap, birds, voles, spiders, squirrels, and frogs.) As the civet's gustatory interest is strictly in the outer, pulpy portion of the coffee fruit, it allows the commercially viable pit (containing two of what we know as the coffee bean), to pass through its digestive tract physically unscathed, though perhaps somewhat morally cheapened. Like the common house cat, the civet habitually tends to void its bowels in the same spot every day. Thus, it's the work of but a moment for cheerful coffee plantation workers to run their fingers through the creature's rich, loamy feces and glean the treasures within, which are then washed (thank God for small comforts), roasted, and sold as "the world's finest, and most expensive, coffee," at prices often exceeding $200 per pound.
