Make kitty cleanup quick, easy, and tidy with the Zero Mess by World's Best Advanced Pine Scented Cat Litter. It has a patented blend of naturally super-absorbent whole kernel corn and plant fibers to trap liquids and odors in tight clumps, with no dust or mess. Designed for high-performance use, this multi-cat-strength litter is lightweight, 99% dust-free, 100% natural, and totally flushable for easy cleaning. By forming clumps quickly, it also prevents the litter from sticking to the litter box. It’s also septic-safe, eco-friendly, and free of toxins or silica so it’s safe for the whole family. Plus, it contains a blend of real pine ingredients for a gentle, natural scent.

Key Benefits
  • Traps liquids and odors in tight clumps with patented blend of super-absorbent corn and plant fibers, with natural pine scent.
  • Uses only clump-forming plant materials with no silica, for a formula that’s 99% dust-free.
  • 100% natural formula uses concentrated granules so you can use less litter and get better performance.
  • Quick clumping action provides powerful odor control while preventing litter from sticking to the litter box.
  • Perfect for heavy duty use and multiple cats, and is flushable for easy cleanup.

Always wash your hands thoroughly after handling used cat litter, as cat feces may contain Toxoplasma gondii—a parasite that can cause toxoplasmosis. Pregnant or nursing women, as well as children and anyone with a weakened immune system, should avoid handling used cat litter. Always handle litter in a ventilated area to avoid inhalation. Keep contents and packaging out of reach of children and pets. Seek medical help in case of accidental ingestion.

  • Best litter

    By on

    The name says it all and it really is the worlds best cat litter. very little smell, clumps well, cats like it, this is the first time I tried the pine scent. its good. it does come with the "California" warning about breathing in the pine and how is causes cancer, but I wouldn't NOT buy it/try it because of that. I don't live in CA and I don't recall seeing this on any of their other "scents". I buy the red bag usually which is unscented. Its great. I have tried all the rest and still go back to the best. A little more costly but in the long run, you don't have to change it as often as other brand.

  • Not for my cat/causes dust

    By on

    My cat is stinky when it comes to her urine and poop. This one says no mess, but I do get dusty paw prints everywhere. The pine smell wasn’t as strong as I was expecting, does not cover up the putrid urine smell. I do love the brand though and would recommend the brand, and the multi-cat formula works great for my cat, plus it is all flushable.

  • This doesn't clump nearly as well as the regular World's Best litter.

    By on

    World's Best is great so I thought I'd try this litter too, figuring it could only be better. This litter doesn't clump well at all. The pine scent is nice and delicate, but it just doesn't form tight clumps at all. I will just stick with the regular World's Best it's better than anything else I've tried over many years of cat ownership.

  • okay...not the best

    By on

    I love love love World's Best lavender scented litter. It clumps well and is fantastic at odor control. I thought I'd try pine scented but it really doesn't have a significant pine scent nor is it close to the lavender scented variety at controlling odor. It seems messier to clean, too. I will still continue to buy World's Best but not this variety.

  • Disappointed

    By on

    I love this brand and company. I've bought this litter in other scents and was very happy. I selected this scent, based on a sale. I will not buy it again. It did not handle the odor like the other scents did... My husband has never complained about the litter box, until I tried this scent. It was also not as "dust free" as the other ones they produce.

  • Good Product

    By on

    The litter clumps well, doesn't stick to the sides like it claims. My only complaint is it doesn't hold the pine smell long for as lomg as I would like, but otherwise keeps the urine smell to a minimum.

  • Cat with allergies RELIEF

    By on

    I have tried so many cat litters. One of my 4cats has an allergy and pillow paw. I do not find this litter dusty at all in comparison to others. Not sure why others posted that it was dusty. I agree that it is not a strong pine scent, though the cats don't seem to mind. This does not work well with my automatic box, I manually scoop twice a day. One request to the manufacturer would be to try to make the corn granules smaller, I will have to switch to another brand if the cat with pillow paw avoids the litter box. Will give an update in a month.

  • Not as good as the regular World's Best

    By on

    I use regular World's Best litter and love it, so I thought I'd try this kind out. The pine scent is nice and it holds odor well, but it doesn't clump as well as the regular WB litter and it's more expensive. I'm going back to the regular.

  • Love worlds best, but was disappointed

    By on

    There was not a big difference in clumping quality/odor control with this litter vs the original versions. I also felt as though this litter was tracked more, despite being advertised as tracking less. I did like the resealable bag, but I’ll stick to the regular.

  • Highly recommended

    By on

    If you have more than 1 cat (I have two), you should try this litter. It's excellent. Clumps easily so litter box is rarely wet. No odor in the house. Cats like it.
