A: not unless you want your toilets to backup.

A: I have used this for decades and have had ZERO problems flushing. However, I only flush clumps. For a full change of litter, I use a biodegradable bag and put it out with the regular trash.

A: I have been flushing it for 4 months now, with no problem. I know others who have been flushing it for a lot longer than that. It is not clay litter; if you don't have some kind of hinky septic system, you should be ok.

A: Great question Stefinitely, the answer is yes! All World’s Best Cat Litter™ formulas have undergone rigorous testing to confirm they are sewer and septic safe. Unlike clay-based litters, World’s Best Cat Litter™ harnesses the concentrated power of corn, so you can simply scoop, flush* and move on with your day!

A: Our packaging is recyclable but only at facilities that offer recycling for #7 materials.

A: It is not recyclable packaging.

A: Thanks for the question! No, it's unscented. Our Multiple Cat Unscented formula is just like the Original Unscented formula (the "green bag"), but it has additional all-natural plant material for enhanced odor control to stand up to multiple-cat homes.

A: No, it is unscented. Although we have only one cat, we prefer the multiple cat unscented formula in the red bag. In our opinion, it seems to keep odors away a little better than the original green bag.

A: Thanks for your question! We recommend keeping 2-3 inches of litter in the box at a time for optimal clumping.

A: World’s Best Cat Litter® does not contain Sodium Bentonite, which is commonly used in clay litters as a clumping agent. The corn's ability to absorb moisture and the natural starches in the corn allow it to clump. World’s Best Cat Litter® contains no harmful chemicals, clays, or perfumes.

A: Hi there, we have had a lot of positive feedback from customers who use our litter with various types of automatic litter boxes. Our litter granules clump moisture on contact and doesn’t stick to the litter box.

A: Hi there! All formulas of World’s Best Cat Litter® are made from whole kernel corn and plant components. We follow all labeling requirements for our products, including Prop 65 labeling which was formerly listed on our Advanced Pine formula packaging as required by the State of California for litter containing wood. This formula has long since been discontinued and currently, Prop 65 does not apply to any of our World’s Best Cat Litter® formulas.

A: Hi there, this depends on the litter box habits of your cat(s). Many of our users don't change the litter box at all, but just scoop and replace with fresh litter to keep 2-3 inches in the box at all times. Others notice with one cat, after about 38 days they will fully replace the old litter with all new. On our website, you can see own in-home tests of how long our litter lasted for a certain number of cats under each formula page. Please reach out with any more questions! custserv@worldsbestcatlitter.com or 1-877-367-9225

A: Because we are made from natural ingredients, litter digested will pass through the animal's system naturally. Although it is not unusual for pets to want to sample or taste the litter when it is first introduced, you will want to make sure your pet is using the product as it is intended for animal litter. If your pet continues ingesting large quantities, we recommend discontinuing use, as it will not meet your pet’s nutritional needs.

A: Yes, World's Best Cat Litter is flushable. We recommend placing only 1-2 clumps at a time in the toilet as a general guide for responsible flushing.
