Crow thats interesting what you say about the silvers , its what i was trying to understand when stubby was on about genetics, i have never had a silver thats lost all its silver guard gairs personally but then been described as a BEW , but i know lots of folks who have had this happen.
The Waardenburg Syndrome i thought effected ferrets what i describe as mitts, the classic white blaze on there heads & the white dots on the insides of there legs , these ferrets come in all colours , so i agree its not a specific problem just effecting '' silver'' ferrets
