Rabbit droppings, or rabbit feces, are the waste products produced by rabbits as a result of digestion. Rabbits have a unique digestive system that involves two types of feces: hard, dry pellets and soft, mucous-covered pellets called cecotropes.

Hard Pellets: These are the familiar, dry, round droppings that most people associate with rabbit waste. They are composed of indigestible fiber and other waste products from the rabbit's diet. Rabbits produce these pellets continuously and usually drop them wherever they happen to be.

Cecotropes: Cecotropes are soft, dark, and have a strong odor. Unlike hard pellets, which are excreted and not typically reingested, cecotropes are special pellets that rabbits produce in their cecum, a part of the digestive tract. These pellets are rich in nutrients and vitamins, particularly vitamin B and vitamin K, which are produced by bacteria in the cecum. Rabbits will usually eat these cecotropes directly from their anus, a behavior known as "cecotrophy" or "coprophagy." By reingesting these cecotropes, rabbits can extract additional nutrients from their food.

Rabbit droppings are an important aspect of rabbit health and can provide valuable information about their diet and overall health. They can vary in size, shape, and color depending on the rabbit's diet and health status. It's important to monitor your rabbit's droppings to ensure they are healthy and to make any necessary dietary adjustments if issues arise.
