This stuff is really the best invention since kitties themselves.
Rich and I both have sensitive noses and with three indoor kitties now, the litter boxes are working overtime. Nothing kills the horrible ammonia smell like a few shakes of the Nature's Miracle litter treatment powder. It's like someone has flipped off the "stinky" switch in your nose. Unlike other baking soda "snake oils" (snake powders?), this stuff actually magically makes the smell go away versus just covering it up.
I just changed out the litter boxes yesterday and had to make a special trip to get more because the paint in the laundry room would peel off the walls without it.
