Some animals, such as rabbits, eat their own feces to digest cellulose contents again. These are termed as ______?

Animals that eat their own feces to extract nutrients that weren't digested the first time, such as rabbits re-ingesting cecotropes to digest cellulose, are called coprophagous or are practicing coprophagy. This behavior allows them to maximize nutrient absorption, including B vitamins and other essential compounds, that were not fully extracted during the initial digestion process.
