7. How does World's Best Cat Litter™'s clumping work?

Made with a patented process, World's Best Cat Litter™ is the only litter made of whole-kernel corn, which means it has a naturally microporous structure that traps ammonia odor in each clump, with no seeping, sinking or sticking to the sides of the litter box. Cleaning cat litter couldn't be any easier! The clumps or balls make scooping extremely easy and convenient.

8. How is World's Best Cat Litter™ environmentally friendly?

World's Best Cat Litter™ is made with natural ingredients from corn and other plant materials grown on American farms. These materials are biodegradable and renewable and they go back to nature when properly disposed and give back the carbon and water, which they used when they were grown (carbon neutral).

When growing, the plant ingredients used for World's Best Cat Litter™ are like wood from the forests, producing oxygen and taking carbon dioxide (absorbed) out of the air (CO2 fixation or carbon sequestration). Thus World's Best Cat Litter™ is part of the natural carbon cycle.

Although a flushable cat litter, World's Best Cat Litter™ encourages responsible disposal in a flower garden or an environmentally safe landfill where off gases are captured and used (carbon neutral).

The makers of World's Best Cat Litter™ are proud to manufacture a product that is safe for humans, animals and the environment ... something made from a renewable resource that is biodegradable. Purchasing World's Best Cat Litter™ provides a healthy, safe litter with no synthetic chemicals, clays or perfumes.

9. Is World's Best Cat Litter™ septic safe?

Yes, World's Best Cat Litter™ is septic safe and flushable cat litter. Its natural ingredients are similar to those for foods, but have a very low nutrient value and will be digested (cellulose fiber and starch) naturally by the natural occurring bacteria in the septic tank system without causing blockages.

It should be noted: most houses with septic tank systems are sized and designed for the expected number of people living in the home. For this reason, it is important to use common sense and not flush too much cat litter at one time or in total as this could overload the septic system capacity.

Tests conducted by NSF International, a third-party certification laboratory, proved both World's Best Cat Litter™ Clumping Formula and Multiple Cat Clumping Formula are flushable and can be digested by standard septic waste treatment systems. World's Best Cat Litter™ can provide the report upon request.

12. Is World's Best Cat Litter™ more expensive than other litters?

World's Best Cat Litter™ is actually not more expensive in the long term because it lasts longer. Clumping on contact keeps the rest of the litter dry. As a result, one 7 lb. bag of litter should last one cat at least a month if properly maintained. World's Best Cat Litter™ customers frequently report that, with World's Best Cat Litter™, they do not need to use as much litter, and as a result, they throw away less and save on purchasing costs. The fact that World's Best Cat Litter™ is a safe litter for people and their cats as well as the environment adds to the total value of World's Best Cat Litter™.

13. Is World's Best Cat Litter™ safe for kittens and older cats?

World's Best Cat Litter™ products are made from food or feed grade ingredients and are especially safe for kittens over 8 weeks of age through "elder" cats.

Regarding older cats, World's Best Cat Litter™ customers have reported that those who had become litter averse (LAS—Litter Averse Syndrome), were retrained successfully using World's Best Cat Litter™.

14. How often do I need to completely change the litter in the litter box with World's Best Cat Litter™?

Frequency of changing the cat litter depends on the number of cats and how frequently the cat(s) uses the cat litter throughout the day/week/month. After using World's Best Cat Litter™ for a period of time, customers should be able to monitor the correct amount of cat litter for their cat's needs. Due to the long-lasting and clumping nature of World's Best Cat Litter™, customers report they change the litter less often than when using other cat litters. If World's Best Cat Litter™ seems less absorbent after a period of use, the customer should change the litter accordingly.
