WORLD'S BEST CAT LITTER™
GENERAL QUESTIONS

  • How did World's Best Cat Litter™ get its name?
    Our company started back in 1996, when a group of scientists set out to create the best clumping cat litter possible. What they discovered was a revolutionary process that turned our natural ingredients into a cat litter that delivered concentrated power for a cleaner litter box—with less hassle and less litter. After several tests with consumers, we quickly realized that our litter could go by no other name, and World's Best Cat Litter™ was born!
  • What formulas of World's Best Cat Litter™ are available?
    We have a total of six formulas available to choose from. Original Series is formulated for outstanding odor control, and offers four formulas:
    1. Clumping formula for homes with one to two cats
    2. Multiple Cat Clumping formula for homes with two or more cats
    3. Lavender Scented Multiple Cat Clumping formula for multiple-cat parents who enjoy a light, all-natural floral scent
    4. Forest Scented Clumping formula, with a fresh forest scent from 100% natural wood fibers
    Advanced Natural Series is formulated for high-performance clumping, and offers two formulas:
    1. Advanced Natural Original formula forms smaller, tighter clumps for fast and easy cleanup
    2. Advanced Natural Pine Blend formula combines high-performance clumping with a blend of real pine for a natural scent
  • What are the differences between Original Series and Advanced Natural formulas?
    To satisfy the needs of all cat parents, we offer two series of products to choose from. Original Series uses natural corn to deliver outstanding odor control. Advanced Natural has added all-natural ingredients for high-performance clumping, making cleanup fast and easy. For more details about Original Series and Advanced Natural formulas, check out the specific product FAQ sections below.
  • What makes World's Best Cat Litter™ environmentally friendly?
    All World's Best Cat Litter™ formulas are made with 100% natural and renewable ingredients. Our formulas contain no synthetic additives, chemicals, clays or perfumes, and they are made from sustainably grown ingredients—not mined or drilled using heavy equipment. We use an advanced, patented process to create formulas that harness the natural absorbency of renewable ingredients. World's Best Cat Litter™ contains no artificial chemicals or silica dust so it's pet, people and planet friendly!
  • How do Forest Scented Clumping and/or Lavender Scented Multiple Cat Clumping formula impact people or pets that suffer from allergies or sensitivities to fragrance?
    Like any new product you introduce into your home, we recommend testing the product to see how you and/or your pets react. Like all World's Best Cat Litter™ products, these formulas contain only 100% natural ingredients. However, if you or your pets are sensitive to scent or fragrances, we recommend using Clumping or Multiple Cat Clumping formulas, which are fragrance free.
  • How does World's Best Cat Litter™ offer concentrated power and how does it benefit me?
    World's Best Cat Litter™ uses the concentrated power of corn to help you use less litter to maintain a cleaner litter box. Our patented production process compresses corn into concentrated granules, giving our litter natural absorbency and long-lasting performance. This allows you to enjoy a cleaner litter box with less hassle and less litter.
  • Is World's Best Cat Litter™ flushable*?
    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!

    While World's Best Cat Litter formulas are flushable and septic safe, we recommend that you place 1-2 clumps in the toilet at a time, allow those to dissolve, then flush. Never put large amounts of litter in the toilet.

    Certain states have requirements around flushing cat litter. The state of California discourages disposal of litter by flushing due to the possible impact of the microbes in cat feces on the otter population.
  • Are there any special requirements for storing World's Best Cat Litter™?
    World's Best Cat Litter™ is a natural product, so bugs may be attracted to the litter if they gain access. Seal the package or store in a sealed container in a cool, dry place. Do not place litter boxes outdoors in humid locations.
  • Is World's Best Cat Litter™ more expensive than other litters?
    Nope! With World's Best Cat Litter™, you get more for your money because it harnesses the concentrated power of naturally absorbent corn for long-lasting performance. One small bag of World's Best Cat Litter™ lasts one cat 30+ days. How? Our patented process compresses highly absorbent corn into concentrated granules, giving you a cleaner litter box with less litter! Quick-clumping and easy-scooping performance means the rest of the litter stays dry, so you use less, throw away less—and spend less.
  • Is World's Best Cat Litter™ safe for kittens?
    World's Best Cat Litter™ products are made from food or feed grade ingredients and are safe for kittens over eight weeks of age. In general, veterinarians do not recommend that kittens under eight weeks old use cat litter.
  • How often do I need to completely change the litter in the box with World's Best Cat Litter™?
    How often you need to change the cat litter depends on how many cats you have and how often they use the litter box. World's Best Cat Litter™ harnesses the concentrated power of corn for long-lasting performance, and customers report they don't have to change the litter as often as with other cat litters.
  • Who makes World's Best Cat Litter™?
    World's Best Cat Litter™ is produced by Kent Pet Group in Muscatine, Iowa. The company is a subsidiary of the Kent Corporation.

  • How is Original Series Clumping formula different from traditional litters?
    Most cat litters are made from clay, which is heavy, messy, dusty and produced from mining and drilling. World's Best Cat Litter™ Original Series Clumping formula harnesses the concentrated power of renewable corn for a cleaner litter box with less hassle and less litter. Original Series Clumping is formulated for outstanding odor control, as is ideal for homes with one or two cats. It is lightweight, dust free and sustainably grown, with no added chemicals. And it's tested and proven flushable* and septic safe for simple cleanup.
  • What is the difference between Original Series Clumping and Multiple Cat Clumping?
    Multiple Cat Clumping contains an added proprietary ingredient that provides added odor control for homes with multiple cats. This ingredient is derived from a natural plant material used for animal feed.
  • What gives Lavender Scented Multiple Clumping formula its fragrance?
    The all-natural fragrance is made of a 100% natural lavender oil blend. The oil blend does not contain any chemicals or synthetic ingredients and is derived from a plant-based oil.
  • Will the oil or fragrance hurt my pet if ingested?
    No. The level of oil/fragrance is extremely low, just enough to keep your room smelling fresh, but not enough to cause any harm to your pets. As with any litter, if your pet shows an adverse reaction or begins to eat the litter repeatedly, please discontinue use immediately.
  • Is this the same as Clumping or Multiple Cat Clumping formulas? Or is it a completely new formula?
    This scented formula is the same as the Multiple Cat Clumping formula, just with an added natural fragrance for people who prefer a scented litter.
  • I started using this formula a few weeks ago, but notice the fragrance tends to go away after a while. Why?
    Due to the properties of natural oil, the fragrance will dissipate over time, particularly when it is left open, like in the litter box. Although the fragrance may lessen over time, rest assured that World's Best Cat Litter™ will still perform as it always has! As with any grain-based product, always store the unused portion in a cool, dry place, sealed in the bag or bin.
  • Are there any chemicals in this formula?
    No. As always, World's Best Cat Litter™ does not contain any synthetic chemicals. It's made with all-natural ingredients—even the fragrance is 100% natural.
  • What is the fragrance in Forest Scented Clumping formula?
    The fragrance is 100% natural wood fibers.
  • What is Forest Scented Clumping formula made from?
    Forest Scented Clumping formula is a blend of all-natural whole-kernel corn and wood fibers. The wood fiber is derived from maple, ponderosa pine, oak, spruce, southern yellow pine and cedar. The corn delivers natural absorbency while the wood fibers provide a natural forest scent.
  • Is Forest Scented Clumping formula natural and planet friendly?
    Yes. Forest Scented Clumping formula is made of 100% natural and renewable ingredients with no synthetic chemicals or perfumes. The kiln-dried wood fibers are a wood by-product that might otherwise go to waste.
  • How does Forest Scented Clumping formula compare to other World's Best Cat Litter™ formulas?
    Forest Scented Clumping formula is similar to our Clumping formula in that it delivers the natural absorbency of whole-kernel corn, but adds an all-natural wood fiber for cat parents who prefer a scented litter. This blended formula delivers the same outstanding performance of other World's Best Cat Litter™ products, but adds a natural forest scent.
  • How does Forest Scented Clumping formula differ from other wood- or pine-based litters?
    Unlike litters made solely from wood-based materials, Forest Scented Clumping formula is unique in that it blends whole-kernel corn and wood fibers to deliver outstanding performance and a natural forest scent. The formula derives its natural absorbency and quick clumping from the corn, but adds wood fibers for a fragrance preferred by many cat parents.
  • Will Forest Scented Clumping formula hurt my pet if it is ingested?
    No. The amount of wood fiber in the litter is high enough to keep your home smelling fresh, but low enough so that it does not cause harm to your pets if ingested. As with any litter, if your pet shows an adverse reaction or begins to eat the litter repeatedly, please discontinue use immediately.
  • How does Forest Scented Clumping formula impact people or pets that suffer from allergies?
    Like any new product you introduce into your home environment, we recommend testing the product to see how you and/or your pets will react. Like all World's Best Cat Litter™ products, Forest Scented Clumping formula only contains natural ingredients. However, if you or your pets are sensitive to certain fragrances, we recommend using our unscented Clumping or Multiple Cat Clumping formulas.
  • I started using Forest Scented Clumping formula a few weeks ago, but notice that the fragrance tends to fade after a while. Why?
    Due to the properties of natural ingredients, the scent will dissipate over time. This is particularly the case if the litter is exposed to air for long periods of time. Although the scent may lessen over time, rest assured that World's Best Cat Litter™ will still perform as it always has! As with any grain-based product, always store unused portions in a sealed bag or bin in a cool, dry place.
  • Why does Forest Scented Clumping formula contain a warning?
    As with other wood-based litters, World's Best Cat Litter™ includes the following CA Prop 65 warning on the bags.
