I've seen many people who buy rabbit food in bulk and use it for litter. They say that it is cheaper that litter, but I myself have never tried it. I found this tip at a Ferret Show in Baltimore,MD. Almost all of the showers and breeders there were using rabbit food. Plant saver tip: The breeder that I bought my kit from has big rocks that cover the dirt in all of his plants. He says that they just walk on top of the rocks now. Michelle Kina & Kobe [Posted in FML issue 0757]
