For the first few years I fed my ferrets the stuff they sell in stores labeled ferret food. This got a bit expensive, so I started feeding them cat food. Then I found out that I could buy 50 lb. bags of laboratory animal food for about $29 ( they last about a year), I've been doing this for about one year (I'm on my second bag). I would like to know what other people feed their ferrets (usual answer is store bought cat food which I don't believe would be any better for ferret bladders than feline bladders).
