As a whole prey raw diet is the healthiest you can get for a ferret I would suggest you switch your vet not your ferrets diet. If you are feeding human grade meat you may need to look at the overall balance of what you are feeding, the idea is to balance muscle meat, offal and bone to get as close to whole prey as possible. A friend of mine calls it Frankenprey LOL This website may help you http://holisticferret.proboards.com/index.cgi? Mary http://www.bristolferretclub.btik.com [Posted in FML 6613]
