Cecotropes are special fecal pellets that rabbits produce, which are rich in nutrients like proteins, vitamins, and essential fatty acids. Unlike regular feces, these soft, clustered pellets are reingested directly from the anus. This process, known as coprophagy, allows rabbits to extract additional nutrients from their food. Since their digestive system initially does not absorb all nutrients efficiently, re-digesting cecotropes maximizes nutrient uptake, crucial for their health. This behavior is especially important given rabbits' fibrous diet, primarily composed of grass and hay.
