Alfalfa feed for rabbits or horses or any other animal can have additives, so you just want Alfalfa with no additives. The size of the pellets are often different for different animals, so some prefer the larger pellets for horses and some the small ones for rabbits, etc. They will all work fine and break down fairly quickly. I would actually love to try the Alfalfa meal, but I can never find the meal around here.
