To Becki Kain and har halitosis ferret: Becki - I'm not sure I know what "sour stomach" is. Are your ferret's teeth clean? ARe you feeding anything that would make the ferret's stomach "sour"? Are there any other health problems - certain kidney diseasess may cause bad breath... There are a lot of chlorophyll products on the market for dogs breath, which you may be able to use in ferrets. I would stay away from human breath mints....
