There are other, less expensive products

Try Nature's Miracle, which you still have to use a lot of, but it works better and costs less.
This is not the regular formula! 
2006-03-15
When I received this item, it was the "Vertical Surface" formula, which is thickened and doesn't soak down into carpet padding well. I tried to exchange the item, but EntireleyPets doesn't carry the regular formula and wouldn't refund me because if you ENLARGE the photo, it clearly says "VS" on the label. You can't use this formula as an area spray, since it dries with residue that the bottle says needs to be cleaned thoroughly before allowing pets near it. The vendor has been pretty uncooperative - I ordered through them directly and they charged me $20 more than if I had ordered through Amazon.com - and wouldn't pricematch their OWN price! Probably will not order from this vendor again.
Ignoring smell of its own 
2006-03-09
Ordered a 500 ml bottle and black light. It worked reasonably well, but not perfect (you first apply Urine-Off, then let it dry then reapply and let it dry again usually several times before cat urine stains are gone). Anyway it worked and I ordered a 5 litre bottle, which does not seem to work at all and customer service does not reply to my mails - very disappointing.
But worst part is almost the smell that Urine-Off leaves behind its almost worse than the urine smell itselft. Still looking for a proper cat urine stain remover!
not perfect yet 
2006-02-09
i personally use this product. i do not think it is perfect, but it works better than the other products i have tried. i have not found any product that will clean the urine stains and smells off my wool carpet and upholstery completely. i find it works best for the occasional "mistake" and if you get it right away.
Great, effortless product

Urine-off for dogs is great! We have a Jack Russell terrier & a chihuahua & when we moved into a new house with carpet from an old house with tile, the dogs didn't know what hit them-- they thought that this was a great thing to pee on! Nothing I could find would get the smell & color out of the carpet. Then I found Urine-off. It is really nice. You just blot up the pee. Then you get your sprayer & spray the area until it's saturated... and that's it! There is no scrubbing, etc. You just spray it, then as it dries, it cleans the spot-- the yellow & the smell are eliminated. I LOVE this product! My dogs now rarely pee on the carpet (just my female when she gets excited).
I would recommend to anyone with a dog!

Nearly Worthless

Here's the deal.... if you let your animals pee on the carpet, nothing helps except new carpet. Trust me on that one- I've tried everything. The enzyme formulas like this are way better than nothing and will keep you sane while Phideaux (French for Fido) grows up, but don't expect miracles. Also - this particular brand is not as effective as a brand called "Urine-Off" - but that is typically $80/gallon. It's the same stuff- my guess is this is less concentrated.
My advice is hold off getting the new carpet until the dog (or the toddler) is at least two years old, but when that day comes, rip the old stuff out, including any plywood sub-flooring that got urine saturated, and start over.
You Must Understand This Product To Use It Well. 
2007-04-18
This stuff is very expensive.
Therefore, you need to understand what is does and why you use it. It is NOT a general pet deodorizer, and it's NOT all you need to use.
YOU MUST USE THIS STUFF FIRST, BEFORE YOU DO ANYTHING ELSE ABOUT THE STAIN.
What Urine-off does that other products do not do is chemically react with the crystalline structures of urine that adhere powerfully to all surfaces, whether floors of walls. It's enzymatic work is to break the bonds of these crystalline structures. And that is pretty much it!
Nothing else that I know of actually does that. Once you have used urine-off properly, go ahead and use some cheaper deodorizer and cleaning stuff: save the precious urine-off for what it is intended to do!
I bought a house that was totally urinated by who-knows-how-many cats and dogs. The place was un-liveable. So I bought it pretty cheap. This was in 2005. I think I paid almost $100 for a gallon of Urine-Off, which is way too much.
But that gallon of Urine-Off paid me perhaps $[...]. OK, $[...].
Believe it.

Wow this is so great. I was surprised at the price, I sure would like to get it cheaper but it sure works. Thank you
Great Product that eliminates the cat urine smell instantly!

We bought a house that reaked of cat urine. We had to tear up all the carpet and padding and them we used a paint roller brush to coat the subfloor with urine-off. It worked like a charm. We let it dry over a couple of days and then put down new padding and carpet and you could never tell their were cats in the house that had a urine problem. Better yet, we have 2 cats that we worried would be able to smell the old urine and start urinating everywhere trying to mark their territory. That never happened! So this stuff works great. I use it on everything that my cats pee on. Once they peed on my sofa and I used this and had it professionally cleaned and you can't tell they peed on it at all. Great product! Well worth the money!!!!
