Zero Odor – Litter Odor Eliminator - Permanently Eliminate Litter Odors with Best Patented Molecular Technology - Pet Safe & Works on all types of litter, 16oz (Over 400 Sprays)

This really works, I'm totally happy with how quickly it diffuses odors. I disliked the 'tracer' scent, reminds me of bleach, but the company sent a note with the product to let me know about the scent and it's NOT BLEACH. It fades quickly, but I think it's unnecessary to add at all. IMO. I will keep using, though, because it really works!!

It really works. I've found that the specific litter I buy which is no dust, plus a natural litter deodorizer, with Zero Odor sprayed per instructions, eliminates odor, all without covering it with fragrances. One of my cats has asthma and I'm sensitive to chemicals, so this combination of products works well.

Bought this because I heard unscented products were better for cats. Unscented litter tends to perform better, and I hoped unscented deodorizers would help make it stretch even further. And this product delivered! It works excellent with Tidy Cats Unscented. I haven’t changed the litter in over a month using these products (I also have 4 boxes for 2 cats, scoop once a day, and circulate fresh litter in once the level drops). This has a slight chlorine scent when you first spray it, but it dissipates very quickly. I like to spray some on top then mix it up, then I spray once more just to make sure this product really saturates all the litter. It does make the litter clump a little but they’re easily crushed if you stir well. The bottle is small so it doesn’t last very long, but since I know it works well with certain litters I might invest in the gallon size. Unfortunately this product didn’t work very well with a scented Tidy Cats litter I was testing. It was the glade one and once the scent faded the odor control became nonexistent. Also on some really humid days the Dr. Elsey’s Ultra smelled HORRIBLE (don’t buy the new formula) and this product alone didn’t help. I had to bring out NonScents powder which smells very strongly of chlorine. But using both products together eliminated all the foul odors. So I don’t think this product can go the distance on extremely bad odors by itself. It works best on common, every day litter odors.

We've tried lots of these types of products, but this one was pleasantly surprising. Some just mask the odor, but this one actually works- just a few sprays and the littler odor does not linger. Has a pleasant smell itself, and the cats don't seem to mind it at all

This does make a difference. I find I'm not smelling the litter box or even the litter scent which I didn't like. I was often complaining about it. I notice I'm not complaining about it constantly to my husband anymore. I do have to spray after some "deposits" but I usually just scoop and spray and smell is gone.

Too heavy chemical smell until it evaporates. But after that it does what it says it does. Odors disappear in moments if not seconds. But expensive.

This stuff is worth every penny. We have two elderly cats who have had urinary challenges as they’ve aged. They have urinated on furniture, rugs, even in our fireplace over time. We’ve addressed the cause of their urinary issues, but I have been extremely frustrated with the lingering smell of urine. I bought this and sprayed it on all the problem areas and it worked like magic, even on very old soiled areas. I will never be without a bottle of this in the house.

Hi, I was so excited to finally find an odor eliminator, specifically from the litter box, that I ordered it right away. Unfortunately, it worked probably the first 4 times I used it. It wouldv spray all right, but no smell. I sprayed it on other odors & nothing!! I was so disappointed as it had a nice clean scent to it. I am ordering another bottle in hopes I'm not throwing good &&& after bad! Just call me a dreamer! Thanks for hearing me out Regina T. Sargent

I use this in conjunction with Rocco and Roxie deodorizing pellets (this has a stronger scent, warning if you're sensitive). I spritz once or twice every time I clean, you really don't need a lot. There is no covering up the immediate post-poop odour (I don't think this is possible lol) but it has essentially eliminated litter-related smells otherwise. This bottle and the spray bottle lasted me nearly two years, definitely worth the investment.

Yes, it is pricy but it works. I am sworn by this product and others from this label. If you want house that is free from smelling like pets or pet urine/poop, this is it. Leaves no second hand smell,just no bad smell

I love this stuff.... I thought I'd just use it to reduce the smell from the litter box but it worked so well I was like "hmm maybe this will work on my dog's bed". Yes it did. It worked in the bathroom after someone had a rough time in there. It worked to get rid of the smell of the perfume in the urine cleaner I used to clean up after my cat. Idk this stuff is magical at getting rid of 100% of smells leaving just nothing. No scent, no worrying about my allergies, no nothing. Just a bit of spray in the air and BAM. Fresh, clean, air. Idk how anyone can say this doesn't work because hot damn it just eats the smell and it's gone. No covering it up, no need to reapply, it's just one and done. Sure if someone goes and smells the area up again an hour later you will need to give it a bit more juice as it were, but man all it needs is a single easy spray.

The 1st product I used which works all together for cat litter box, perfect to destroy cat odor. Immediate blocking, I spray on the litter, and all around litter box. I have been using this Spray for a while and the only thing to say here is this is amazing product, considering my cat business is really in "horrible smelling" ones.. I am grateful to Zero! Will do stock of this.

Excellent product! I have 3 cats using a very large litter box. Two or 3 sprays daily keeps the odor from becoming an issue. So much better than the powdered brands! I've used everything and this works better than any other product I've used.
