I use Heinhold Wool Formula with my rabbits, however, other feeds may be used. I feed a 3/4 cup of feed per day. I also feed alfalfa or hay daily to help break down wool that has been ingested so they don’t get wool block. One of the things I have also found useful is to feed a quarter-cup of wild bird seed (I buy mine at Wal-Mart) twice a week. They love it and will usually eat the bird seed before the pellets.
Treats are always enjoyed by rabbits, however, too much of a good thing can cause diarrhea. Various treats can consist of: carrots, dried bread, crackers, apples, corn, corn stalks, grass, banana, dried pineapple, etc.
