Rabbits produce special soft fecal pellets called cecotropes that they consume directly from the anus - a vital nutritional behavior that is often misunderstood as coprophagy but is essential to rabbit health.
Cecotrope welfare is a subtle but important area: the behavior is natural and essential, yet is commonly misidentified as abnormal coprophagy and discouraged by uninformed owners. Preventing or interrupting cecotrope consumption harms rabbit nutrition. When owners find cecotropes in the cage uneaten, this signals a welfare problem - either the rabbit cannot physically reach them (obesity, arthritis, pain), or the diet is producing abnormal cecotropes, or the rabbit is unwell. High-carbohydrate, pellet-heavy diets with insufficient hay alter the cecum fermentation environment, producing cecotropes with reduced palatability and nutritional value. The rabbit's digestive system is exquisitely sensitive to diet composition, and inappropriate feeding creates a cascade of cecum dysfunction that undermines the fundamental nutritional strategy of this hind-gut fermenter. Good cecotrope production, palatability, and consumption is an indicator of good digestive health.
