Alfalfa is offered in local feed stores in a "pellet" form, (Compressed, dried) I took a handful and put it in my coffee grinder, to make it a fine powder. If you don't want to buy such a big (40Lbs) bag, I am sure you can order from Amazon, or get a small bag of Alfalfa from a pet store, which offers items for Rabbits.
