Marshall Pet Products Goodbye Odor Small Animal Waste Deodorizer

We have been using this product for over 10 years and (obviously) love it. We’ve used it for rabbits and hedgehogs. It’s very simple to use and the animals don’t seem to notice the taste. It’s money well spent to get rid of the smell.

I have to admit, that when I was first urged to buy this product at a local pet store, I was really skeptical it was a useless waste of money that wouldn't perform as advertised. However, my little Guinea Pig's cage didn't have the nicest odor even with just a little pee and poo in it (and we are meticulous about the regular cage cleaning), and I decided to give the product a try. Well, between using this "Goodbye Odor" in the piggy's water, and switching from pine shaving bedding to the Carefresh Natural, there is a night and day difference with how much nicer the piggy's bedding smells now. My daughter acquired four pet rats, and their urine and poo is pretty rank, too. We use cloth type bedding for the rats and it was getting smelly, even after changing the litter boxes and bedding daily. So, we added a bit of the Goodbye Odor to their water and it has been much nicer! One bottle lasts us months too, as one squirt per day in the water bottle or bowls works just fine. As for ingredients, they appear to be safe with the main ingredient derived from button mushrooms. There are other ingredients such as de-ionized water, dextrose (a sweetener derived from corn), malic and citric acid (which I believe are present for pH and some flavoring, especially the citric acid) and then some Potassium Sorbate as a preservative. We have purchased a second bottle on Amazon.com now and will likely be purchasing more. I enjoy having pets, but it is nicer if the house doesn't smell like a barn, especially when company comes over!

This product really works! It has virtually eliminated the cage odor of our 3 female rats. The product does not deter them from drinking their water at all. On the contrary, they are only interested in the water bottle that contains GoodBye Odor, and have been ignoring their other bottle with plain water. Knowing how well it works and that the rats are staying hydrated, we'll be mixing it into all of their water from here on out. UPDATE: After several months the odor was becoming stronger and stronger. It seemed like to product was no longer working. We stopped using it for one week. When we started using it again, it was extremely effective. Once in a while your animals may need a break from the product to "reset" their systems, but don't stop entirely!

Works great. I add three pumps into my rats water and that's all there is to it. I do this every time I change their water. Pros: 1. Lessens and perhaps for some people comes close to eliminating the smell in a small animals habitat. 2. Price isn't exorbitant for what you get. I feel it's a good value for the results I'm getting. 3. Very easy solution to a common problem that many other products can't do much about. 4. Appears to be all natural and will not harm your pets. Cons: 1. Product's bottle could use a redesign or they should just get a new one that isn't as cheap. I understand that they need to keep costs down, but turn it upside down and the product comes out of the bottle even when the top is screwed on tight. My first shipment of this was packaged with some other things I'd bought and the bottle leaked all over everything in my shipment. The next one I received was covered in so much tape to avoid the leakage that it appears this is a long standing issue that could easily be addressed by changing to a new bottle. 2. For me the product itself has a strange not to pleasant smell, but that's not why I bought it :) Conclusion: I love it. I have 4 Rats and they have a rather large Habitat, but like to dirty up the same spots every day and it gets smelly. Only after a week of using this I've noticed a HUGE decrease in odors coming from their habitat. Others in my household have also confirmed the results. I recommend it to anyone that has 1 or more small pets that smell things up.

I didn't realize how much this stuff really works until I stopped using it for a few months. I used this for about 3 years for my many pet rats. At the moment I have eleven, but sixteen was the most I had at one time. They are about 80% litter trained. I don't know what possessed me to stop using this (probably the amount of money I was spending on this product, having to re-fill several 16 ounce water bottles almost daily). Anyway, within days their poop smell became very noticeable and stinky! It was pretty bad! I recently ordered two bottles of it and in less than two weeks I'm beginning to notice a decrease in odor. This stuff is worth it's weight in gold and I will never stop using it again. Note: The only drawback is that it does leave some residue in the water bottles that needs to be cleaned with a bottle brush. Also, I highly recommend using glass bottles (which is healthier than plastic).

CRUELTY PRODUCT TESTED ON BEAGLES, FERRATS AND ECT. I WILL NEVER BUY ANOTHER MARSHALL PRODUCT. THEY ARE THE LARGEST ANIMAL TESTING LAB IN THE US

we keep our guinea pig cage in my sons room with 2 male adult guineas in it. we change the pine in the cage every 7 days. before using this product, by day 4, the room smelled terrible. we constantly have open windows and large fans circulating the air out of the house. we have been using this product since it got here, about two full weeks. the difference is ASTOUNDING!! here we are at day 7 and time to change the pine/clean the cage and there is a very minimal amount of smell! I wish I could buy this stuff in bulk, since it is kinda pricey. however, it is totally worth it not to smell them anymore! I will continue to buy this product. I think we will probably go through a bottle a month.

Works good, can tell the scent has decreased while using. Pricey though

Perfect to reduce ferret odours

Removed ferret smells!!it actually works

Helps with the smell a lot doesn't take it away completely through. Also leaves a slimy film in the water bottle, but does the job.

I have been using this product for my 4 male pet rats and it has made a difference. There was a reduction in smell after using it in their water for two weeks. They still have a rat smell to them but their poos have a sweeter smell and its less offensive. I will be buying another bottle once this has finished. I do recommend putting it in their water rather than food as you're less likely to forget to give it them and you know everyone in the cage is getting some.

No problem with the seller, however I have found that the manufacturer of this product is unethical and runs intensive farming small animal operations to supply not only the pet trade but the lab research industry. I will not be putting any more of my money in their pocket as I don't support those ethics. The product itself is not great, so I won't be sad to not buy it again. GoodBye Marshall Pet products.
