A rabbit's diet should be made up of good quality pellets,
fresh hay (alfalfa, timothy or oat), water and fresh
vegetables. Anything beyond that is a "treat" and should be
given in limited quantities.
Pellets should be fresh, and should be relatively high in
fiber (18% minimum fiber). Do not purchase more than 6 weeks
worth of feed at a time, as it will become spoiled. Pellets
should make up less of a rabbit's diet as he or she grows
older, and hay should be available 24 hours a day.
When shopping for vegetables , look for a selection of
different veggies--look for both dark leafy veggies and root
vegetables, and try to get different colors. Stay away from
beans and rhubarb. Here's a suggested veggie list.
Hay is essential to a rabbit's good health, providing roughage
which reduces the danger of hairballs and other blockages.
Apple tree twigs also provide good roughage.
If sufficient weight is maintained, continue adult diet
Frail, older rabbits may need unrestricted pellets to keep
weight up. Alfalfa can be given to underweight rabbits,
only if calcium levels are normal. Annual blood workups
are highly recommended for geriatric rabbits.
When you feed a lower quantity of pellets, you must
replace the nutritional value without the calories, which is
done by increasing the vegetables. Also, a variety of hay and
straw must be encouraged all day long, we do this by offering
fresh hay a couple of times a day.
