Marshall's and Four Paws make a Deodorizing and conditioning spray for ferrets. They both do a wonderful job of conditioning and deodorizing the ferts. You can also spray a bit on bedding to help keep odor down. It doesn't take much. Hope this helps. I use it when company comes over or when they are itchy and not really needing a bath (shedding).
