Designed to thrive on grass and leaves in the wild, which are relatively slow to break down, rabbits rely on a double digestion process to get the most nutrients out of their ‘poor quality’ diet.
Caecal pellets — a special type of soft droppings — are produced in the caecum of the rabbits’ digestive tract and usually re-ingested even as they are excreted. Resembling tightly-bunched grapes, these pungent, mucus-coated pellets contain beneficial caecal bacteria.
The second time round, pea-sized faecal pellets of undigested fibre are passed out. Rabbits use these dry, easily-crumbled droppings to scent-mark their territory.
