Black light question
Ok I got Nature's Miracle and have been using it on my rug where I know the cat peed. Then when we brought in the new kitty from outside - my cats began peeing everywhere!! So I have treated every place I thought they peed with Nature's Miracle.
Then I went and got a black light (didn't have time to before) and am shining it everywhere and can't see if they've peed anywhere else. Would it come up as a black spot under the black light? This black light mostly just picks up everywhere that cat hair is hidden!
