You are down to subfloor, or have you put down new carpet?
I am assuming you removed the carpet, the pad...how 'bout the tack
strips? WHat did you put over the subfloor, and what is the subfloor?
Wood or concrete?
You have to *seal* the urine in the subfloor. It cannot be removed. No
enzyme, mask, cleaning product, or neutralizer will remove dried
alkaline urine salts in either wood or concrete.

Ah, from someone who moved in after 9 cats...
1) Get the old carpet up
2) Get the old tack strips up. Use a wonderbar.
3) Look around for subfloor areas that are black. Replace these.
4) Go to your local hardware store, get a 5 gallon (depending on the size of
your house),
a broom handle, and paint roller kit.
5) Put a nice liberal coat of water sealer over the entire subfloor. Don't
be bashful
about it.
6) Open the windows and abandon the house overnight. Don't forget the
canary.
Don't waste your money on enzymes, they don't work.
You are hired. (-;
Don't use, however, a water sealer that is silicone based, like
Thompson's Water Seal. I use xylene, (respirator w/*fresh*
cartridges!!!!) because it will *never* permeate the odor...not even
from dead body contamination/crime scenes. Sorry about being graphic,
but after a few hundred of these jobs, there is only one way, and
Scott is right.
You will *NEVER* remove dried alkaline urine salts from wood or
concrete. They have to be sealed so heat and moisture do not activate
the *source* of the odor which you *cannot* remove.
*Seal* it. If you *don't*..."I'll be *back*!"
On walls/baseboards, an alcohol based pigmented shellac. KILZ will do,
but I think BIN works better; has a better gas permability factor.
If you check the bottle of Nature's Miracle you will see the main
ingredient is acetic acid, which, essentially, is household white
vinegar.
Spray the area in question and let dry. You may have to repeat this
process as an attempt to get the mixture into the floor as deep as the
cat urine (are we talking finished wood floor or wood subfloor?)
Good Luck!

I don't know about Benz, but Kilz is not exactly easy to work with. I'd
recommend
using a respirator with it, and make sure you have some mineral spirits
available
to at least clean your hands. I was using for the first time late at night,
and didn't
think I'd EVER get that stuff off me. I even tried gasoline, and that
didn't work.
What does the silicon based water sealer do/not do that xylene does? Is
that stuff
available to Joe Public? I just grabbed the cheapest 5 gallon can of sealer
I could find and
it did the job.
Of course, after I put new carpet down, I had to trim the bottoms of several
doors. The Urine
smell was trapped in the door bottoms (eww).
Whatever sealer I used, it worked great, considering that the carpet felt
like it was soaked
with vaseline (double eww) when a friend of mine and I pulled it up. I
still feel sorry for the
carpet guys that hauled it away in a box van.
In the basement, I mopped everything down with a bleach solution. That
seemed to help quite
a bit.
BTW--I don't think you could afford my billing rates from work... ;-> I
don't come cheap.
OTOH, I feel I probably saved $10,000 in fixing the problem versus the
previous homeowner
doing it, so it really was worth it. Now I've just got another $15,000 of
real renovation to do, and
I'll have a really nice house.
KILZ or BIN is not "easy" to work with, but then the problem is a
difficult one. In order to smell, a substance most be, even to the
slightest degree, soluble in water and lipids; if it is not, it will
never get past the water/lipid barriers over your olfactory nerves.
All odors are activated in the presence of heat and moisture, which is
why odor will suddenly "appear" when it has previously not been
present, when the proper conditions are met.

Silicone is used as a true water-"proofer", and is quite effective at
it. Which is why such things as tents, camping gear, raincoats, canvas
awnings, etc, are often siliconed, as water will not penetrate
siliconed surfaces. In carpets and rugs, it should NEVER be used, as
soils actually bond to the silicone, and become impossible to remove.
If you have ever tried to clean a real soiled tent, say, you know how
difficult it is to clean them.
In this work, silicone will *not* prevent dried urine salts from
offgassing to the air. A different type of *sealer* must be used.
Whatever you used, it probably was not silicone, or you would be
smelling urine. The restortion industry tried and rejected silicones
years ago for sealing odor sources.
SIlicone will bead water, and is the best water proof treatment I know
of. Put a drop of *oil* on a silicone treated surface, and it will
*instantly* penetrate.

With **9** cats, I am surprised all the walls were not saturated.

Maybe the residue of a couple hundred attempts with enzymes....

Next time, use an *acid*; bleach is alkaline. The dried urine is
alkaline. To clean and remove, we *neutralize* pH. Bleach treated
concrete surfaces will not remove dried urine salts; we use an acid
used to clean pipes and porcelain...mild enough to be handled bare
handed, if one would wish to do so.
*Really* nasty concentrations: a much more concentrated acid to
literally etch the concrete surface.
But even vinegar will work quite well, in cleaning the surface of the
concrete. Of course, there are still *billions* of dried urine
crystals in the porous holes in the concrete you can *never* get out.
If you cannot *eliminate* the source of the odor, it *has* to be
sealed.

*Neither* do I.

If it is bad as what you have posted, it can *easily* hit that price.
I did one for $38,000. Cleaning, neutralizing, sealing can run to
$2.50--7.50 per square foot. You still have cartage and disposal.
Replacing carpet, pad, tack strips. Cleaning walls and baseboards.
Sealing and painting them.
I have a lady who 6 months ago rejected a bid at $850 to clean and
seal a bedroom. She simply replaced the carpet, and now her house
smells like urine, *again*, and her cat has died. Her *new* carpet is
contaminated by the subfloor. Unfortunately, she is going to have to
pay *twice* for what could have easily been done right, the first
time.
Now your original post was *exactly* the method used to control large
urine contaminations, and I just found it remarkable that someone
figured out the proper way to *control* the problem. It is difficult
for many homeowners to understand the problem, because we all think it
is just a simple "wipe-up and it is gone" type of problem. The source
of the odor is microscopic, and is virtually unremoveable, so it has
to be *sealed* to control odor formation.
Fortunately, with my case, they had "upstairs" and "basement" cats.

I don't know what it was, except one of the grossest things I've ever
dealt with.

Doesn't that make the area smell like a salad? That's almost going
from one extreme to the other...

Yeah, I managed to pull this little rabbit out of my hat in 2 weeks while
spending a lot of time out of town. It was a rather busy time, carpet
removal, tile setting, cleaning, sub floor replacement where it was
really bad (A guy helping me almost throwing up into a corner was a
good sign it was really bad). I think the carpet layers recommended
the sealant method. I think 90% of it was in the carpet/pad/bad parts of
the
subfloor.
I've still got a bunch of paneling to replace (it needed it anyway), and
one of these days I'm going to get the air ducts cleaned out, then things
should be really nice. That and a kitchen and bathroom...

No, it lasts no longer than it takes to dry. Did your floors smell
like bleach forever?
When you clean items, you really neutralize pH, which is *why* most
home cleaning products, and professional ones, are alkaline...usually
the strongest cleaner in a home is ammonia, with a pH of someone
between 11.0--12.0. Most *soils*, and soils being all sorts of things,
not just dirt and sand, are acid in pH.
Urine is acidic, then transforms over time to an alkaline. It is
*better* to use stronger acids than vinegar, as they are more
effective.
<SNIP>
Your work was the right procedure. You did a good job, especially with
that many animals. I had two cats which did $38,000 worth of damage to
a home.
Good luck with your remodeling...
