Masks Odor

Definitely makes a difference in cage odor. Her cage had such a strong urine smell before I found this product.

My Guinea is now mad at me

My Guinea Pig did not like this. He refused to drink his water and squeaked his discontent at me.

Tastes like bleach

I bought this thinking that if it worked it would be wonderful. Put it in the water and thought it had an odd smell. I dipped my finger in the water to taste it and I gagged. Imagine if every time you were thirsty and went for a drink the only liquid available to you tasted like bleach? Absolutely awful and anyone who cares about their pets would not force this on them.

My guinea pig don’t like the taste

My 2 guinea pigs were not even drinking the water after I put it into their water. Total waste of money.

A must try!

I love my little guy Rizzo, but he's cage just smelled. And, I was cleaning it every 2 days. GOODYBUY B & W is great! Just a few squirts in his water bottle was all I needed. Actually, it's recommend by veterinarians so it's safe to use. Rizzo is an adult male rat so his hormones are raging. He urinates everywhere in his cage, even though he's got a litter tray and poops in there. He didn't smell so bad when he was a baby. It will take a week or two on it before you can smell the difference. GBye does seem to leave a film on the glass in his water bottle. I got a baby bottle scrubber for it to use at water changes. I noticed there's a DIFFERENT formula for ferrets too. It's made by the same company.

Noticed a Difference Right Away!

I have an indoor rabbit. Of course with that comes the unpleasant aroma of their urine. I read the reviews for this product and thought I would give it a try. OMG... I am amazed that this product really works. I add it to Penelope’s water, she doesn’t even notice the difference but I sure do! Truly reduces waste odors! She’s happy, we’re happy, total win. :)

definitely noticed a difference

I used this in my piggies water for a whole month and I noticed the area where they eat and drink was much less smellier, but I wanted to make sure this product actually worked. I stopped using it after that first month and boy did they smell, I think the smell was worse too lol. Definitely recommend trying it out, it won’t completely erase the smell but definitely tones it down (by a lot) until the next time I have to deep clean the cage(once every week), did not notice any side effects in my guinea pigs, and I would use the recommended amount of pumps to add in the water.

Seems to help

Our mini lop bunny did not want to drink his water when we first added this. We used the max 5 pumps in regular sized water bottle. It must add a different flavor because it doesn't smell great. We use 3 pumps now and it seems to be helping in combination of a good litter to minimize odors. Leaves a bad odor in water bottle so wash out every day or so.

Mice and hedgehog

I had an unused bottle laying in my room for a while. Only two weeks ago did I decide to give it a try. I did not follow this to the letter, because I use much smaller volumes of water. For me, just adding drops of this to the water made a huge difference. The lack of stank now is incredible. I used to have to wash the mice wheels everyday just due to the smell alone, but now I don’t feel that I have to do that. I think this is a must have for small animal owners. The smell between cleanings is so much less and with a good cage cleaning schedule you wouldn’t know I share a room with small animals. :) I don’t know everyone’s situation, but I think it would be important to consider if your pet itself is clean and healthy before you knock the product usefulness. I’ve had great results.

This works perfectly!

This product helped so much with my rabbits odor. It was a big problem and I couldn't find anything that would work. I found this and tried it out and ever since, its been a lifesaver. I recommend this product! All you do is put 3 to 4 pumps on their food and water and just like that, it gets the job done.
