Clumping or Non-Clumping

Clumping * Non-Clumping * Which to Choose

Cat litter comes in two basic types: clumping and non-clumping. Each has advantages and disadvantages. Litters come in a wide range of materials with very different properties when it comes to length of use, odor control, etc., so be sure to compare each material too.



  • Allows you to remove only the used portion of the litter when cleaning the box.
  • Often considered long-lasting because of the ability to leave unused litter in the box.
  • Gives a visual cue for how much your cat urinates, allowing you to spot potential health changes early if the urine clumps change in size or frequency.


  • Many clumping materials, like Bentonite clay, can be dusty
  • Can stick to cat’s fur, which is a problem for kittens, or cats with mobility issues that prevent proper grooming



  • Often available in totally dust-free materials
  • Some varieties of non-clumping litter are inexpensive
  • Generally considered a safe choice for kittens, or for cats recovering from injuries or surgery because it’s less likely to stick to their bodies


  • Many non-clumping litter materials are not good at controlling odors
    • Some litters will have added ingredients to mask or suppress odor
  • Often requires frequent total box changes to stay clean/fresh
  • Some varieties of non clumping litter are expensive
