, produced in the cecum
, of some mammals that ingest a high-cellulose diet
. The pellets are ingested (a process
referred to as refection or coprophagy) as they are eliminated, providing additional time for symbionts
to break down cellulose. It has been proposed that one primate
, Lepilemur, is a coprophage, suggesting caecotrophic pellets
may be ingested.
