Without going too much into my personal opinions on using ferrets as food (I've kept ferrets my whole life and am the proud owner of two currently, so I have to agree with piedpython), this is a really really terrible idea. Have you ever been bitten by a ferret? Raising them from babies, before they are trained out of biting, they have incredibly strong jaws, and it's very hard to get them to let go of something if they are determined to hang on to it. They can be very good at killing and I have friends who have had ferrets bring wild lizards or snakes to them that they've caught around the house. Even between my male ferret and my three year old boa constrictor, I'd place my money on the ferret (not that they are ever given the chance).
