This did not work

I've tried so many of these products that I've decided to leave reviews. This is just one of the many products I have tried for cat urine. This one DID NOT work. I used it on my hardwood floors, tile, and furniture, no damage to anything. It does have a very strong scent which at first is okay. It's been months and it still smells, and it did nothing for cat urine, seem to make the problem worse. I use the fresh scent also, which smells like fresh cut grass. Neither of these products worked.

Urine Protection

I've had cats for years. My favorite and last of many left is a 14 year old Russian Blue who has the strongest smell urine in the world. NOTHING , I mean, NOTHING removed his smell until I discovered this product through a You Tube presentation from Danelle who is a Master Cat Groomer, has her own school and is know through out the world for her cat grooming classes. I'm telling you this works. Some reviews has complained about the smell but truthfully I do not and never did find it offensive plus it does not linger for long!!

Surprise...Works for ants too!

I had an incontinant elderly cat that I needed to clean up after and this product worked. I made the concentrate into a spray bottle and used it to clean up after my 20 year old cat. It worked great for getting rid of the smell and had a tolerable fragrance. Other odor control products have offended my nostrils. Last week I woke up to an army of ants on my counter and grabbed the spray bottle that I had this product in as it was close by and sprayed everywhere I saw those nasty little beasts. I was pleasantly surprised that they have not returned since. I know that's not what this product was designed for, but I'll definately use it again for ants at my house.

Cat Odor Off Love It

This was recommended to me some time ago and I didn't know where to buy it. Now since I've found it I'll never be without it again. This stuff is fantastic! It is sooo much better than what it out there on the market today. It gets rid of the cat odors, in carpets, on the sofa, on the outside where those pesky outdoor cats that come around leave their mark. No more smell. And because it is measured, it has lasted me over 2 yrs. Now that is a savings.

Awesome product!

I have 5 adult cats and have had a couple litters of foster kittens the past few months. My adult have had issues urinating inappropriately and this stuff is great for cleaning up those messes and keeping the cats away! I’ve cleaned my entire house (counters, floors, furniture and litter boxes) 3 times already and have only used half the bottle!

Have used for over 15 years- it works

I have used this since a recommendation from my holistic vet circa 2002 as this is what they used in their office. It saved my housemate's leather couch when my older cat started using it instead of an over full litterbox.(my bad). I followed directions and it worked! He said the couch smelled better than before as well. I have continued to use Thornell Cat Odor Off over the years with now multiple cats in many settings and situations and it absolutely works- I rely on it. I use it on outside-the- box urine, spray, vomit, to clean litter boxes and travel crates, and launder cat beds and fabrics which got peed on. Using has helped me save rental deposits and leave a hotel room with no lingering cat smell. By the way, the company has white paper full of research and testing documenting how the product works. This is not just a me- too product. It seems other brands have paid a lot for retail space in the major retailers and so I could not find it in stores, but the professionals had it- which says something about effectiveness to me. For years I mail ordered it directly from the company - until now that it is on chewy - at a better price with faster free shipping! I am happy about that. I recommend getting both the soaker bottle and the big concentrate bottle so you can refill the soaker bottle when you run out. I also just want to say that: Just because one product dominates big box retail pet stores shelves does not mean it is better; it only means they pay retailers a lot of money for shelf space, or the company is aggressive in its marketing.
