I use Bi-Odor and love it. We have 10 personal ferrets in my bedroom and 12-15 downstairs and you don't smell anything. I also use with my rats now, and it has cut their odor down to nothing. Great Product-High recommendations here. I buy it in the gallon size and refill my bottles as needed. It is cheapest that way. We also sell it for our ferret rescue for a great price on ebay. Sorry, another plug, but if I can save people money......It is normally $34.00 for the bigger bottle, which we sell that same bottle for $24.99+Shipping. Still make out better with us. Profits go to our Rescue group.
