Why do rabbits eat their own soft feces?

During the raising of domestic rabbits, we see that the hard fecal pellets they excrete are formed through a second round of digestion. Domestic rabbits eat grass and feed during the day, and at night or before dawn they excrete soft feces, and as soon as the soft feces are excreted, they immediately eat them; only through the second round of digestion and absorption do the residues form hard fecal pellets that are excreted from the body. When domestic rabbits eat the soft feces they have excreted at night, it is not a coprophagia habit caused by a lack of some nutrient in their body, but rather a normal physiological phenomenon. This instinct of domestic rabbits has two major benefits: first, it can keep the rabbit hutches and rabbit farms clean and hygienic; second, it can achieve the effect of making full use of the feed. Therefore, during the raising of domestic rabbits, if you find them eating the soft feces they have excreted at night, do not disturb or stop them; otherwise, it will disrupt the digestion pattern of the domestic rabbits and affect their normal growth, development and health.
