I've been using Marshall's Bi-Oder deodorizer for about 9 months and have actually notice diminished ferret smell. I can find it only at NEEPS the Ferret Store. I have 6 sweet ferrets (poop machines). I clean their cage daily - they use newspaper in the corners- and wash the hammocks once a week. They get in the shower with me every morning, therefore I don't bath them very often. I like the product. I mix about 6 'pumps' with about 1 cup of warm water, ferrettone and their vitamins for their moring "soup" and they look forward quite eagerly. Regard....
