Best for litter boxes!
I love this product. I have 3 cats and have and issue with one cat that pees on the floor (she is currently on medication to resolve this) this is all in my basement along with the litter boxes. It stunk! I got one of the plugged it in a week later you would never know there was litter boxes down there. I love this product! It does hum but it is not noticeable and it emits a blue light.
