Doesn't work

It did nothing for the smell. The cats didn't like it either and wouldn't use the litter box with it in it.

I am always excited to try new products for my cats and do my best to provide them with a safe and enriching environment. That being said I am disappointed in the brand world's best for creating this product and also chewy for selling and promoting it with lemongrass. I am not a veterinarian but with just a tiny amount of research you can see lemongrass is mildly toxic to felines. Scented litter is also not recommended as it can irritate cats sensitive noses aswell as pose other health risks like recurring UTIS. With this knowledge I decided it was not in my cats best interest to use this product. I did however open it and it does smell pleasant. I poured some into a sock and tied it up and put it in my dresser drawer and it makes my clothes smell nice! So atleast there is that. Over all I would give this product a 0 and would not recommend to anyone and it has caused me severe distrust in chewy, yet again another company who prioritizes profit over safety.

I was using the World's Best Odor Fighter Litter but decided to switch to their non-tracking option, which is unscented. If smell is your main concern, use the Odor fighter litter. If you need a bit of the "best of both worlds", this works great. Just have to remember to add it every week when you scoop.

I wanted to wait and use the product (World's Best Cat Litter Booster) more than once to review. Ive used this product along with my regular scoopable litter. I scoop every night to keep odors away. This product gave me so much more use out of my litter. I am able to scoop nightly and not worry about odors for at least 10 days. Previously I was doing a full litter change about every 4 days. Now I can scoop and refill for 10 days maybe even 2 weeks before having to fully change the box saving me alot of money on litter. I have 2 cats and Ismell nothing ! If I could use it as litter I would !!! It smells so good and it actually looks like colored cat litter. My Girls are sensitive to scents and they have sensitive skin. This product does not bother them at all. A little bit goes along way. Ive had my bottle almost a month and I still have more than half of the product left. And did I mention it SMELLS SO GOOD !!!

Im giving a 4 star because i honestly cant tell if it is or isnt working. The scent is fine and the cats dont seem to mind it layered on top of their litter. I do like it better than the powder deodorizers because i feel the cats are more prone to accidentally inhaling it or something and this is more like tiny rocks. An actual litter type os product and not powder. I still scoop as normal and i feel it still smells as it normally does from day to day. I tried to give it a few days to see if i could notice anything but im not sure. Maybe im cleaning my box too often to notice. Either way, i do like the consistency of the product more than normal deodorizers and the cats dont seem bothered at all.

I have a multi-cat household with 3 litter boxes, so I was excited to see if this would help mitigate some of the odors. I clean the boxes consistently every other day and use a multi-cat litter. This product is great for the poo odors; I definitely have found that it has been consistent for reducing those odors. The granules are a perfect size for intermixing with the litter, both fine texture and regular clumping (I use both because one of my cats is a tripod and the course litter is uncomfortable on his missing foot). However, for some reason, the ammonia smell from the urine seems to be intensified in the boxes where I have used this. I don’t know if it might not be compatible with the type of litter I use but it is something to note.

At first I was skeptical, because I was not sure that our cats would tolerate the lemon grass smell, but they did not seem to mind at all. We have two cats, and upon using the scent beads in the litter they did not mid at all and used the box as normal. When I use this product I put a small amount of litter in the box then I sprinkled the beads in then I put more litter on top. Right after I clean the box our cats got in did their business and had no problem with it. There was no smell and there still no smell of urine or waste and it’s been two weeks now. I would highly recommend this product to anyone who has had prior problems with cat box smells, or to someone who has a multi cat home. This product is definitely worth it.
