As long as her energy is up, and her weight loss hasn't been a sudden,
new development, I wouldn't worry about it...I also have a skinny
albino male -- I call him a furry skeleton -- but this is the way he's
always been, and his activity level is normal.  He has been to a very
knowledgeable ferret vet, too, who said not to worry about his
skinniness... I just wish I could give him some of MY extra weight
that I don't need!
 
Take care,
Chana
