If you are working toward a more natural lifestyle and diet for your family, it makes sense to extend that to your pets.  Rabbits are a perfect pet to transition to a natural diet, and in most cases you can feed rabbits on much less money when you get away from commercial pellets.  In the wild, a rabbit will eat mostly green leafy foods, with occasional grains and vegetables.  This is one of the easiest diets to replicate in captivity and you will probably see a noticeable improvement in your rabbit’s health once you make the switch.Grains
Rabbits need a little grain in their diet, but it is by no means a large portion of their diet and should be strictly rationed.  My rabbits eat a custom mix of barley, rolled oats and black oil sunflower seeds mixed together in equal parts.  Over the summer, I fed a handful of adults and about 18 kits and am down to two does right now, still eating the same 150 pounds I mixed in May.  I imagine there is probably almost two-thirds of the mixture remaining, so a little goes a long way.  Every other day, I give them a cup or two.

Greens
During summer, you can pasture yours like we do and let them have free choice access to greens, or you can go the easier route and pick fresh greens for them.  Dandelions, alfalfa and clover are all tasty choices the rabbits will love.  In the summer, we feed free choice alfalfa hay in addition to their pasture so they don’t ever run out.  In the winter, they get free choice alfalfa with the handful of grain every other day.

One thing these foods don’t have that is present in commercial feeds is a complete mineral supplement.  For that, you can buy a tiny wheel of salt at the feed store for under 50 cents.  Make sure they have constant access to the mineral block, fresh water and alfalfa and supplement a little grain.  My rabbits are sleek, healthy, and enjoy a wide variety of foods to keep them interested in eating.
