Review on Marshall Pet Products Goodbye Odor Natural Water Supplement for Ferrets and Small Animals: Effective Deodorizing Solution by Stephanie Brown

We have been using this product for several months and have noticed a reduction in the smell of urine in the guinea pig cage. We forgot to reorder and decided not to. At first we didn't notice a big difference. But then it was very noticeable. Cell odor after 2-3 days without drops = odor after 7 days with drops. As with some medications you take, the benefits are not very noticeable until you stop taking them. Then you really see the difference.
