Does NOT work well for cat urine! Wavelength matters!

First tip: UV wavelength MATTERS for cat urine! (Keep Reading)
My cat peed on my new shag rug, and before I wanted to take a cleaner to it, I wanted to know exactly where to clean, so I bought this. I received it, waiting until night, turned off all the lights (yes the urine was totally dry). NOTHING SHOWS. I know there is pee on the carpet, because she smell is strong. This doesn't even glow a little bit. I'm so disappointed. It makes lint and white socks glow, but that's about it. It shows human urine and dog urine, but that doesn't help me much. It tested it on the litter box, it has a ever so slight green glow, but I'm not relying on that faint glow to detect pee for cleaning.
After I've researched, cat urine should use a wavelength of 365-385!!! How can they fail to advise customers of this before they buy? This product is 395 and is too high to visibly show cat pee! Now I have to order a new one and wait even longer before I can properly clean my rug. I'm returning this.
