Caecotrophy refers to a nutritional process in which some animals, such as rabbits and rodents, consume their excrement as a means of obtaining additional nutritional benefit. Though it may seem odd and uncomfortable to humans, this process is critical for the digestive and metabolic systems of these animals. While "caecotrophy" is a precise term used in biological contexts, there are numerous synonyms that may be used to describe this process, including coprophagy, autoingestion, and cecotrophy. These terms may be used interchangeably to describe the act of consuming excrement, depending on the specific context in which they are used.
