We've been using rabbit food for several months here...and I'm pretty much in love with it. The smell is wonderful, it kills odors, it's very absorbent. My ferrets haven't nibbled on it, but if they do, it's meant to be digested, so it won't cause a blockage. The ONLY thing I've noticed that could be a problem is that it tends to stick to the bottom of the litterbox when it gets wet. I use a shop-vac to empty my boxes, so it's not a problem for me. I think this can be avoided by putting a little of that fluffy newspaper type stuff underneath the alfalfa...it should keep it from sticking. The price was pretty good too, we got 50 pound sacks for $5....and we bought 350 pounds of it. Hope this helps, Melissa [Posted in FML issue 2901]
