Cecotrope
Cecotropes , also caecotrophes or night feces, are the product of the cecum, a part of the digestive system in mammals of the order lagomorpha, which includes two families: Leporidae ( hares and rabbits), and Ochotonidae ( pikas). Cecotropes are passed through the intestines and subsequently reingested for added nutrients in a process known as "cecotrophy", "cecophagy", "pseudorumination", "refection", or coprophagia. Reingestion is also practiced by a few species of rodent (such as the capybara and guinea pig), marsupials (particularly their young) and possibly two species of primate (gorillas and chimpanzees).
