Less is good(smell)
I have four fuzzies in one large cage and they share a litter box and this helps a lot with the odor. Just a few pumps in they're water is all it takes

Highly Recommended
When I brought two new ferrets in to join my other 4 I noticed how bad their waste smelled like ammonia. Within 3-4 days it went away once they drank the water I always use this product in. I am going to buy the gallon now, as it is $20. cheaper than the 32oz.x 4= gal.The young couple I got them from only had them 2 mths. I am sure this is one of the reasons they got rid of them. One is 2.5 & the other is about 5 yrs. They were with another family before the young couple too. Such a shame. Now they are in a perminate home and happy with the others to play with.

Works great in food and water!
We started with a small 8oz and now have a large 32oz and this stuff is great and non-toxic for the fuzzies. We put it on their food (which gives a little bit of smell) and in their water. Their litterbox smells like flowers and is very fresh! They love their food and water and this has not affected them at all and we love the fresh scent of the house!

I can tell when im out of it.....
I purchased this with the advice from a ferret owner and ran out last week and wow does it make a difference . very very big must have. well at least for my boys.

Wow! Skeptical no more.
This stuff really does work! I was skeptical, it sounded too good to be true. My ferrets live on the 8-1 Ultimate diet, and since they started eating it, their poo has been extremely foul. I stumbled upon this by chance, and decided I'd order the smallest bottle just to see if it works. It really does. My female noticed it in the water and wouldn't drink it though, but I decided to only use 1-2 squirts instead of the 3-5 in their giant water bottle and they stopped noticing it. After two days I could not smell them anymore! Naturally their poo still smells, but it's not over-powering and doesn't smell up the room anymore. It was thanks to other peopls reviews that I decided to give it a shot, though still skeptical. There's not much to lose in trying it, I would reccomend it to anyone that has a problem with over-powering ferret smell. They're such great animals, but because they do stin, a lot of places wont let you have them.

propylene glycol
propylene glycol is also found in make-ups, shampoos, conditioners, body washes, soaps, and much more. Just letting you know. If you wana talk about something being harmful remember its in everything you use. It works. The critters are healthy. So what does it matter.

Does NOT anti-freeze component
A previous reviewer stated that one of the ingredients, propylene glycol, is a component in anti-freeze. That is NOT true. It is ethylene glycol that is in anti-freeze. The REAL facts are that propylene glycol is approved for human consumption but ethylene glycol is poison. Google them for yourselves.

Going to try this product out since it got good reviews

I am a huge believer in this product. I used it for 3 months in my ferrets water and it truly took the bad odor away from his urine and poo. (it takes about 1 month for it to work and cycle thru your ferrets system) I ran out and kept for getting to order more for like 2 months and the bad odor came back. I am definitely stocking up on and will not run out. REALLY WORKS GREAT!

Manages odor between baths. Monitor closely for health affects during use of this supplement.

I use it in the water servers.

Goodbye Odor works in reducing odor from Guinea Pig waste. The cost of gallon is a large saving.

This really works and of course it is Marshal Farms. The best brand name of all others for ferrets.

This product works great. Pet stores charge $16.00 for a small 8 oz pump bottle.
Lynn W on Mar 28, 2014
Saw this product and since it was on sale I thought I would try it. The outcome was great. It does exactly what it claims to do. When I walk into my house after work I don't smell the ferrets anymore.
