Allow me to RAVE about this awesome product that outperforms everything else out there (and I have tried them all). I have bought this 4x now, tried the combo pkg first but I just buy the cheape 16oz concentrate now. One bottle of concentrate makes many, many 32oz spray bottles.
I was skeptical about the proprietary oils, but it is truly not a mask, perfumed coverup or fizzy enzyme type like oxiclean. I use Simply Green for my housecleaning, and I use Cat Odor-Off to erase anything cat-related or organic that smells bad.
This product finally eliminated ancient hidden pee smells that came with this house and got really ripe in hot weather. It removed it under the baseboards %26 quarter rounds, grooves in the LVP flooring, around walls/door frames sprayed by tomcats, in the concrete of the house %26 patio slab, wherever nothing else worked. Also smelly beds %26 blankets. I spray on freshly cleaned litter boxes %26 cat carriers, also freshening up after scooping %26 stirring litter between whole box cleanings. It's not that there are extra strong chemicals (who wants that anyway?); it is just a combination specifically made for cat-type smells, and they make other formulations of products for other smells. Cat Odor-Off neutralizes smells but doesn't confuse the cats or make them sick.
I don't like perfumes either, and this just smells clean.
You can use as often as you want since it's inexpensive. When your spray bottle gets low, just mix up another spray bottle full and don't worry about it, because 16oz of concentrate makes so many 32oz bottles. It's a little tricky at first because the concentrate is in a special bottle, so follow label directions on how to tilt %26 squeeze that big bottle to fill the little measuring reservoir without wasting. (You can also mix up soaker for upholstery in the same proportion %26 use a pour bottle instead of a spray.)
It is totally safe. They have come out with a Fresh scent now besides Original. Fresh smells like linen, is not citrus which cats don't like, but I prefer Original which has a little vanilla smell but is not sweet. Just be sure to buy the CAT Odor Off with a CAT on the label if it is for cat pee because the manufacturer makes many specialized odor removers.
*One note, the ads say it is even safe to spray directly on animals, but I would not do that because they will always lick %26 swallow it.
But honestly when I think of how much $$$ I've spent on things that didn't work, plus the frustration that comes with living with animals (who you would never dream of living without), their behavior problems %26 accidents because they don't know any better...but you still want a pleasant house... This product helps us all coexist happily. Animals don't want to live in nasty homes either. I see why vet clinics use it.
Just make it easier on everybody and invest $23 in one 16oz concentrate. By the time you have turned it into about 15 bottles from that investment, you will be convinced. It's state of the art.
