Thank you, Suki -- Yes, the bone meal I'm using is Solid Gold. I have trouble getting my workers to grind bone, and it has been easier, if more expensive, to use the bone meal. The ferrets do get some organ meats and cartilage -- we use everything on/in the chicken. Do you think that is adequate? I'll have cooked eggs added to the mix. How much per ferret per day? Your info on the fats is literally a lifesaver -- we have been giving them beef fat. Thank God it has only been about a month. What oils are ok? Do you think that including the entire skin gives enough fat? The meat mix is 2/3 chicken and 1/3 beef. Do you know whether beef fat is ok for cats and dogs? [Posted in FML 7187]
