This deodorizer for my cats litter box was easy to use. I took away a star because there are no instructions, so I didn't know how much to use. I just shook some in and hoped for the best. The stuff has an odd smell close up, but I didn't notice that it was overpowering onece I put it in the box. It did seem to help to cut down on the smell of the litter box.
It doesn't add a heavy fragrance, but simply neutralizes the odors. The cats didn't mind it. It's an all natural product so it's safe for my cats. Overall I thought it worked pretty well, but had I had some instructions it may have worked even better.You can find it on Amazon Here.
I received this product for free for my honest unbiased review.
