Rabbits are herbivores and grass and hay are major parts of their diets. Pellets, generally sold for domesticated rabbits, can be fed to wild rabbits, but they are a high-fiber concentrated food source that should not be given in excess.
Wild rabbits that are six months or older can be fed a variety of vegetables if they are introduced slowly. Suitable vegetables include watercress, parsley, carrots and beets. Cruciferous foods such as broccoli, cauliflower and cabbage should be avoided, as they can cause gas, stomach pain and even death in wild rabbits.
Rabbits are commonly more active at dawn and dusk. They are heavy grazers, particularly in the late afternoon. Rabbits pass two forms of droppings, one type of which is then reingested to help them digest the large amounts of cellulose they eat and to provide them with extra vitamins and nutrients.
