Hi,

Maybe someone here can help me. I need a UV light that shows cat pee
in the dark. Something high-quality that will actually work. I've had
disappointing results in the past with supposed "urine finders" that
don't show anything.

I was researching this online and found a site that seems to be
impartial (dedicated to helping people deal with their pet issues
rather than trying to sell a product). They recommended the GE
F15T8-BLB fluorescent UV bulb. Has anyone here used this bulb, and
did you find it useful? If you haven't used the GE bulb, can you
recommend a reliable brand?

(The site that recommended the GE bulb was:
http://www.sprayalert.com/finding-cat-spray.html )

I've already bought a big honking bottle of Nature's Miracle and have
dumped a bunch of it (twice) on the place where the pee was. However,
days later, it still smells of pee - now mixed with the smell of
Nature's Miracle.

I'm not sure what that indicates:

* I didn't get all the pee areas? (That's what the UV light would
help with.)

* The pee soaked through the carpet and into the wood floor? (From
what I've heard, that would be a disaster.)

* Nature's Miracle isn't so miraculous? I couldn't have bought a more
appropriate kind, as this one is meant specifically for feline urine.
Are there other products as good as (or better than) Nature's Miracle
that might remove the odor?

Thanks!

I think you need what they call a, "black UV light". This is because you
need one that doesn't emit a significant amount of visable light, which
would make it hard to see the dim florescence that the cat urine
generates. I found this on wikipedia:

Ultraviolet radiation is invisible to the human eye, but illuminating
certain materials with UV radiation causes the emission of visible
light, causing these substances to glow with various colors. This is
called fluorescence, and has many practical uses. Black lights are
required to observe fluorescence, since other types of ultraviolet lamps
emit visible light which drowns out the dim fluorescent glow.

all uv lights are called black lights.

i bought a bunch of these, and they work well.
