## Questions & Answers

**Q: What are the ingredients? And why are they not listed? Seems shady to me... I'd rather use an all natural product anyway.**
A: Re: Reply below, and if this stuff is the same as the A & H Carpet Cleaner...
It is not.  The two have totally different fragrances/smells, and also differ (at least to me), in appearance.  Carpet Refresher seems to be more fine of a powder, compared to the Litter Box Deodorizer, or just plain old A & H Baking Soda.  I used to use the “Fresh-Step” brand, when I could get a box of 9 for just over $20, on Amazon.  Over the past several years, the price of that stuff skyrocketed!  I like it a bit more, but not so much that I’m willing pay that much more for it.  I looked around, tried several different products, and settled on this one—smell is nice, without being overpowering, and if you keep an eye out, you can get it from Amazon for a VERY reasonable price (way cheaper than the big box pet stores).  Most importantly however, my (indoor only) cats are not bothered by the smell, and took to it right away.  I still buy the big, 13lb bags of plain A & H Baking Soda, because I like to line the litter boxes with a THIN layer of it (especially the ends and corners—for some reason, my three cats believe it is proper litter box etiquette to direct their pee there) before I add litter to it.  I then use this mixed-in at the top of the litter, and a little bit after “quick scoops”, between real cleanings.

**Q: What are the ingredients in this please?**
A: Hey there Jennifer! This product contains: sodium bicarbonate, perlite, distillates, petroleum, hydrotreated light paraffinic, hydrated silica, and fragrance.

**Q: How is this different than regular baking soda?**
A: There's a citrus-like scent to it that isn't overpowering at all. It  does a nice job, and seems to last longer than just baking soda.

**Q: How frequent should I apply this?**
A: as often as you want. I recommend adding when you clean it out, after scooping
