Review on 🔍 Unleashing A Fresh Start: Discover Marshall Ferret Bi-Odor! by Tony Wylie

8 oz. The formula sold at Petsmart, Marshall Good Bye Odor for Small Animals, works great. It is slightly thicker than this formula and has a slightly pearly cream color. The seller informed me that this is the same formula as the rebranded Marshall Good Bye Odor for Small Animals, so I ordered a gallon-sized Marshall Ferrite Bi-Odor for Ferrits and Small Animals. It can't be the same formula. We started with the same amount as the Petsmart version and it didn't work so we increased it, then increased it the next week and doubled it again within two weeks after that. We are now doubling the amount used in the Petsmart version and it doesn't seem to help at all. The smell remains as strong as before using the Petsmart version. Maybe this version actually works with the smell of ferrets, we have rabbits; but since it's about ferrets and small animals, it should work. I do not recommend purchasing this product if you have pet rabbits.
