Oryctolagus cuniculus is a generalized herbivore, eating a diverse diet of grasses, leaves, buds, tree bark, and roots. Gardeners know them to eat lettuce, cabbage, root vegetables, and grains.
Although the diet is relatively low in nutritional value, and high in indigestible material, O. cuniculus is one of several rabbit species that are known to reingest feces (coprophagy) to obtain extra nourishment from their food. The species has a very large caecum, in which bacterial fermentation of otherwise indigestible material occurs. Periodically, the contents of the caecum are defecated and reingested. These rabbits are thought to depend upon this process for some essential nutrients, which are released or produced by bacteria and absorbed on this second pass through the digestive system.
