The rabbit cecum is a fermentation organ essential for nutrition and health, and its proper function depends entirely on adequate long-stem fiber intake that most commercial rabbit diets undervalue.
Cecal health is the foundation of rabbit wellbeing: a rabbit with inadequate hay intake is compromising its fundamental digestive architecture, creating conditions for a cascade of health problems. The marketing of pelleted feeds as 'complete' rabbit diets has led generations of rabbit owners to undervalue hay as the central dietary requirement. Pelleted diets, even high-quality ones, do not provide the long-stem fiber that drives normal cecal motility - the physical scrubbing action of hay moving through the cecum is as important as its fermentable fiber content. Young rabbits are particularly vulnerable to cecal dysbiosis: inappropriate weaning diets, stress, and antibiotic exposure can all disrupt the developing cecal microbiome with fatal results. The welfare solution is simple but requires consistent owner commitment: unlimited high-quality hay available at all times, with pellets as a supplement rather than the dietary staple.
