Suki posted to me that loss of fur was hormonal and some other causes
other than diet.
 
Unfortunately I have to fully disagree with that where I have had diets
of ferrets that did cause loss of fur.  Byte-me loves tomatoes.  I was
feeding her about all she wanted but she lost all her fur from too much
of the red stuff.  I stopped feeding tomatoes and shortly after her fur
began to come back so diet can adversely affect the coats on these
animals.
 
I do not intend to argue this point with anyone but to express my
findings, you make your own conclusions and good luck for the little
guys you keep.
