World’s Best Cat Litter Advanced Natural Original Cat Litter Review

Last Updated by Brandon F. on June 10, 2020

Advertised Product Description

This is our World’s Best Cat Litter Advanced Natural Original Cat Litter Review.  World’s Best Cat Litter Advanced Natural Original cat litter takes a more natural approach while still promising the meet the high expectations of its litters.  Using corn, plant fibers, and wood, this litter promises to produce outstanding clumps and odor control while being great for the environment.  Other benefits include being flushable and 99% dust-free.  It is available in 6, 12, and 24-pound bags.

Who This Cat Litter is Intended For

This cat litter is designed for those owners who want to go a more eco-friendly approach in the cat litter for their single or multiple cats.  However, in doing so they don’t want to give up clumping abilities or odor-locking features.  Also, it is good for those who are turned off or allergic to the artificial perfumes that are commonly included in the litter.  Finally, it is for someone willing to spend a bit extra for a product that works for them.

What Makes This Cat Litter Unique

This product is unique because it combines a variety of natural ingredients including wood, corn, and plants into a product that still retains its clumping ability.  This is somewhat a rarity as many all-natural litters fail at clumping because of a lack of clay.  We enjoy seeing these litter manufacturers think outside of the box sometimes and try combining several somewhat uncommon materials into one product.

Clumping Ability – 1.5 star

Unfortunately, this formula doesn’t seem to clump as well as most of the other World’s Best offerings.  Perhaps by going “all-natural” it came at the expense of clumping.  Specifically, moisture seems to break down the litter into an almost saw-dust like material that simply doesn’t adhere well to cat waste.  This results in very soft and sensitive clumps and some cases no clumps at all.  This is one case where not going with a “harder” substance has hurt the performance some.

Scent – 2 star

The litter itself isn’t overly appalling despite not using perfumes.  However, it can struggle with masking cat odors after a couple of days.  This is likely connected to the weak clumps.  When the litter breaks down all of the waste odors can be kicked into the air and also mix with the wood fibers to create a very foul smell that will turn most cats and owners off.  While the clumps are in one piece, however, it does manage to hold in most smells but timely removal is required.

Messiness – 1 star

This is a very dusty litter, especially when the litter starts to fall apart.  The dust can get kicked up everywhere and is small enough to be breathed into one’s nostrils and tracked all over the place.  This can be quite an issue if you are using this in a busier litter box as you’ll experience tracking all the time.  Also, the very soft clumps mean that removal can be quite dicey and you might end up with a huge mess.

Value – 2 star

There is a rather large range of online prices for this product.  However, we mostly see them falling in the mid to premium-priced ranges.  This brand of cat litter does take a somewhat different approach but as you can tell from our reviews some glaring issues don’t justify the higher than average asking price.

Overall Rating – 1.5 star

The World’s Best Cat Litter Advanced Natural Original Cat Litter Review earns 1.5 cats out of 5.  We are disappointed with this litter, especially considering how well its sister products are.  The decision to go “all-natural” comes at a hefty price here and that price is lackluster clumping ability, difficulty masking scents, and an overall huge mess.  If you are in the market for something more eco-friendly we encourage you to keep looking. tests and analyzes every major cat litter brand and various cat litter accessories to determine what the best product is that meets your needs.  When readers choose to buy our independently reviewed choices, we may earn affiliate commissions that help to support our writers and site maintenenance.
