my Urine Gone review

I like the stuff - now keep in mind I initially bought it cause of my old dog with a leak. The humidity we've had this summer has made my house smell horrible and keeps my allergies running overtime.
So I went into the room Sadie prefers (which has a ceramic tile floor) and ran the bluelight and the specs that showed up gave me a cause for fear.
I sprayed the "urine" out of the room and the house smells so much better and specs are disappearing.
Can't determine about cat urine smell...and my litterboxes don't show anything with the blacklight. But some of the doggie pee has been there, in the grout, for awhile cause Sadie's leaking started a couple of years ago and last summer was really bad.
