Game-Changer for Eliminating Cat Odors – A Must-Have for Pet Owners!
As any indoor cat owner knows, the struggle with litterbox odors and the lingering stench of out-of-box accidents can be a constant battle – often feeling impossible to truly eliminate. But let me tell you, this cleaner is nothing short of a miracle worker. Our beloved cat recently suffered from a bladder infection, which unfortunately led to a few unwelcome accidents on our cherished wood flooring. We were bracing ourselves for the worst, knowing how stubborn that particular odor can be. However, from the very first application, this product completely blew us away. It didn't just mask the smell; it eliminated it instantly and, crucially, kept it away. Days later, there's no trace, no lingering hint that anything ever happened. Even better, none of our other cats have returned to those spots, which is a huge testament to its effectiveness in removing the scent marker that often encourages repeat offenses. This concentrate is incredibly potent, meaning a surprisingly small amount goes a very long way, making it both effective and economical. Seriously, if you're a cat owner dealing with the persistent challenge of urine odors, look no further. This product is an absolute game-changer and an essential item for maintaining a fresh-smelling home. Highly, highly recommend!

The BEST thing you can purchase for your home!
Shocked is an understatement! I have read and seen many reviews on this product and wow. I have both a dog and a cat, and my cat had a period of time where she was incredibly stressed with the arrival of a new puppy. This product works GREAT. It got rid of any smell of animals or/and urine from potty training. A little goes a LONG way, so it’s really worth the price. Crazy affordable. I have the Fresh scent, and it smells AMAZING. I’m really sensitive to smells, and even with the carpet soaked with this stuff, my airdoctor shows clean quality air, which is insane. Fresh, clean, best product out there. Wish I had it sooner!

Better and cheaper than fabreeze
Love this stuff, works well will getting rid of that litter box smell and works great as an air freshener. Pretty good price for the amount of spray bottles I get out of it and the scent isn’t overbearing and it keeps fabrics smelling nice for several days
S**!
Works and smells great
Works and smells great so far when use as directed. It does not completely get rid of cat urine smell and smell does come back after a few days no matte how I use product and temperature does effect it. On hot days, the urine smell comes back stronger than not hot days. I like the fresh scent smell of product and how it's not chemically smelling like other products. It is expensive for product, just wish it works better for getting rid of cat urine smell but for now it will have to do until I find something that works better. FYI: I've tried just about every thing and product out there and nothing has worked for cat urine smell and odor.. sighhh

Absolutely Fantastic
My husband and I just bought a fixer upper and.... well, the lady that lived there before had 10 cats and let them do their business everywhere. So you can imagine the intensity of the odor. We could smell the odor from OUTSIDE the house. I know that cats are actually clean animals and prefer clean litterboxes to go potty in, so I know that these poor animals did this because they had no other choice. I can almost bet that their litterboxes were never cleaned. I honestly feel bad for them. It's clear that the previous owner either had mental or physical problems, or had absolutely no pride in their home or pets because there's a lot we need to do. A sad situation all around. Anyway, our first order of business was to get rid of the odor so we can do other work in the house without smelling like cat pee every time we leave. I sprayed everything with this stuff and noticed a difference immediately. I used a garden sprayer (the kind that you use to spray pesticides and such) and soaked all the subfloors with the concentrate. 1 gallon takes 4 ounces of the concentrate. I used 2 gallons full for the first sweep (this place is 1120 square feet). Now, we can still smell some urine, but I believe it's coming from the materials we've pulled out of the place, sitting in garbage bags on the porch for now until we can get them to the dumpster. After all the material that we need to pull out comes out of the home, I'll go through with another round of this odor remover. And finally Kilz Restoration everything so we don't get anything sneaking back. Yes, the odor is that bad. I'm totally amazed with how well this stuff works and I highly recommend it! It has a light fresh smell that isn't overpowering and certainly smells better than urine.

Eliminates smell and cleans great!
OK at first I was a little bit skeptical but this stuff works amazing! Feels totally clean after using and takes away all of the smell! I use it in the backyard in a sprayer that attaches to my hose, as well as in my mop bucket inside my house!

In comparison with the other urine eliminator brands, I like this best because of its scent. It eliminates the urine odor and gives a fresh scent in the area. However, it did not stop my cat from spraying around the house so I am not sure if any of this product work for my cat.

We have a cat that the kids love but I want to boot because it pees territorially because of its sister and its ruined so much of our stuff. I nearly drenched the house with this stuff after wandering around at night with a UV light and though our house smelled like a vet clinic for 3 days. The smell went away and suddenly that lingering pee smell was gone. We did a big clean and wipe and carpet clean and we have noticed way less with the UV light now! I highly reccomend! The smell is almost sweet from this product.

Works exceptionally well I tried it on several surfaces that are usually hard to keep fresh (stroller, litter mat, yoga mat, floors) and it removed the odor completely every time. What I really love is that it doesn't just mask the smell, it actually eliminates it. Product is easy to use, leaves no residue, truly effective. Absolutely worth it.
