Asian palm civet also called toddy cat, is a small member of the family Viverridae native to South and Southeast Asia.
Individuals weigh from 2 to 5 kg. It has a body length of about 53 cm with a 48 cm long tail.
Their sharp claws allow them to climb trees and house gutters.
Asian palm civets are believed to lead a solitary lifestyle, except for brief periods during mating.
They are both terrestrial and arboreal, and nocturnal.
They are omnivores utilizing fruits such as berries and pulpy fruits as a major food source, and thus help to maintain tropical forest ecosystems via seed dispersal. They eat chiku, mango, rambutan and coffee, but also small mammals and insects.
Kopi Luwak is coffee prepared using coffee beans that have been subjected to ingestion and fermentation in the gastrointestinal tract of the Asian palm civet, which is called luwak in Indonesia. Caffeine content in both Arabica and Robusta luwak coffee is lower than in unfermented coffee. Large deformation mechanical rheology testing revealed that civet coffee beans are harder and more brittle in nature than their control counterparts indicating that digestive juices enter into the beans and modify the micro-structural properties of these beans. Proteolytic enzymes cause substantial breakdown of storage proteins.
