As it is lactose that is the problem I shouldn't think raw milk would be any different to regular pastuerised, or other treated milk. However the vast majority of the lactose is in the liquid part of the milk so cream is a good supplement in a ferret who is underweight. A spoonful of extra thick cream did my V a workd of good when he had an upset tum in the summer this year. [Posted in FML 6163]
