Questionwhats some other things that you could use on a ferret for there odor
AnswerDon't bath them more than once or twice a year. Wash their bedding every week or more often (they should be in sheets, towels etc). Feed them a high quality food like Natural Gold, Totally Ferret etc and make sure you clean their litter box often.
Other than that, ferrets have an odor just like any other animal.
