Cecotropes, also called caecotrophs, caecal pellets, or night fecs, 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", coprophagia or "coprophagy". Reingestion is also practiced by a few species of rodent (such as the beaver, capybara, and guinea pig), some marsupials (the common ringtail possum (Pseudocheirus peregrinus) and possibly the coppery ringtail possum (Pseudochirops cupreus)) and one species of primate (the sportive lemur (Lepilemur mustelinus)).
