3 Best Clumping Cat Litters Reviews

What is a Clumping Litter?

Clumping cat litters are generally non flushable, such as the clay type. The main characteristic of clumping cat litter is the fact that they form firm clumps when in contact with urine or feces, keeping the surrounded litter clean. However, the litter box needs to be emptied and refill with new litter every 15 days or so to prevent bacteria formation.

Most clumping litters are made from granulated bentonite clay which gives them the fast clumping characteristic. Clumping litters help saving on litter since only the clumps in the litter box need to be scooped, leaving the rest of the clean litter in the cat box.

If you want to choose cat litter to use with your automatic litter box you may want to choose premium clay clumping litter for best perfomance of these machines. Here you’ll find a comparison between the 3 best:

Ever Clean’s granules contain bentonite clay, activated carbon/charcoal and borates. The activated carbon goes through a manufacturing process which puts the carbon inside the clay granules. This process is called “agglomeration” and gives Ever Clean’s litter the capacity to absorb and hold odors.

Additionally, the formula contains an odorless antimicrobial agent to prevent bacteria formation.

The consistency of this litter is a sand type that clumps effectively, and due to the carbon filter inside the clay granules, all the moisture gets held, creating clumps that won’t break apart when scooping.

Boxiecat clumping cat litter

Boxiecat clumping cat litter

This clay clumping cat litter is soft and easy on your cat’s paws, especially suitable for declawed cats. One of its main characteristics is that cats take easily to this litter, keeping a low amount of dust and helping to reduce the litter tracking due to its heavy weight.

Boxiecat is a healthier option for cat owners that prefer a clay cat litter with hypo-allergenic natural ingredients that don’t have harmful chemicals or additives.

This cat litter comes in sizes 16 lbs and 28 lbs. The varieties are unscented, gently scented and extra strength odor control. This review is for the unscented.

Opening on corner for easy pouring

Opening on corner for easy pouring

The special formula creates a hard flat surface that doesn’t allow liquids to leak onto the bottom. The litter creates firm clumps that don’t break down while scooping, avoiding the mix of a dirty litter with clean litter.

Boxiecat litter has been developed with a dust suppression technology to reduce dust when pouring and when your cat digs in it.


  • Clumps are formed on surface and not to the bottom
  • Fast clumping
  • Low dust, but not dust free
  • Firm clumps that don’t break down when scooping
  • Soft sand type litter it’s easy on cat’s paws
  • 16 lbs is easy to handle and with zip sealing
  • 28 lbs with corner opening for easy pouring and handle
  • Reduced litter tracking
  • No fragrance (a “pro” if you don’t like fragrances)


  • Price isn’t low
  • Litter is quite heavy
  • Low dust but not dust free (it has a little more dust than for example, Arm & Hammer)
  • Some customers claim it doesn’t really cover odors well
  • Clumping on litter surface technology is a “con” when the wet litter gets in contact with the sides or the edges of the litter box, it sticks to it like glue, making it very hard to scoop.
  • One bag is needed to fill a large litter box (with 3” deep of litter)


Boxiecat works as advertised regarding hard clumping on the surface of the litter, but it seems like the odor control is not optimal and the dust is low but not dust free as advertised.

This clay clumping litter forms big hard clumps to isn’t recommended to use with a rake type automatic litter box due to the effort the machine’s motor would need to do, but it may work better with an automatic rotating litter box system. However, as this litter is heavier than others and consequently you will need to put less in a rotating mechanism, it may not work very well if your cat likes a deep litter bed, so if you use this litter with a rotating auto litter box make sure your cat doesn’t mind a shallow litter bed.

As a note, to fill one large regular litter box you need one 16 lbs bag so you may want to consider on buying the bigger size of 28 lbs not to run out of it.

Boxiecat is a good clumping litter for cats that need a softly sanded litter and for cats that don’t take easily to any type of litter.

This litter may not be suitable if your cat is used to urinate on edges of the litter box.

A good thing is that you can save money in Amazon if you buy this litter through Subscribing & Save.



Clay Clumping. These litters are made from bentonite and are not flushable. These litters create solid clumps that absorb and retain humidity making it easy to scoop and clean the litter box.

Some claim that clumping litter could pose a health risk to pets when inhaled or ingested in small amounts, but there is no scientific evidence that can support this claim, even the ASPCA (American Society for the Prevention of Cruelty to Animals) using clumping litters for years hasn’t had or presented any case of health issues with clumping cat litter.

If you want to use an automatic self-cleaning litter box, clay clumping litters are the most suitable for this purpose.

Pine and Cedar based litters. These litters are environmentally friendly and smell very nice. Cats love the wood smell which attracts them, but this nice smell disappears when in contact with urine or feces which creates a stinky litter box.

Another problem with this type of litter is that they are sticky and create tracking not only on the cat’s paws but around the house and they are hard to scoop because the clumps break apart almost completely.

Corn-based litter. This litter has an unusual smell of litter that isn’t a fragrance or anything like that. Corn-based litter does very little to cover cat’s waste so extra odor destroyers are needed to keep the litter box’s odors under control.

Corn litter is very lightweight and creates corn dust that can elevate up to the door if your cat digs enough, covering also the cat itself. The worst part is that corn-based litters help in developing feline acne.

Crystals. This litter has a good capacity to absorb liquids but its consistency isn’t soft on the cat’s paws and some cats hate using this litter. If your cat has sensitive paws it could even develop behavioral problems and refuse using the litter box.

Pellets. Either silica, newspaper, etc, pellet shaped litters made from any kind of material pose the risk of the cat chewing on them and eat them, plus cats don’t like using the pellets that much, especially when time to dig and cover their feces or urine.
