  • Why use sodium bentonite clay litter?

    Sodium bentonite naturally exhibits the scent-trapping properties of baking soda, so there’s no need to add chemicals or perfumes. It forms hard, tight clumps fast and locks in odor by drawing up liquid and isolating that telltale ammonia smell. We take great care to preserve these qualities during the drying and sifting process, so you can be sure there’s nothing better for your cat or your cat’s litter box.
  • Is this litter safe for my cat?

    Our premium cat litter is safe for your cat because it is all-natural, with no added chemicals or perfumes. In fact, it’s only made with one ingredient: sodium bentonite clay, dried with the power of the sun. The only time you may want to be careful using our clumping litter is when you have a very young kitten. Kittens sometimes eat litter, and if they ingest clay-clumping litter, it can expand in their stomachs and cause harm. Until your kitten is several months old, you may wish to use non-clumping or plant-based litter.
  • Why is clay-clumping litter better than silica gel?

    Cats generally prefer unscented, clay-clumping litter to silica gel and other types of litter because the clay texture is most similar to sand or dirt—which is what your cat’s wildcat ancestors have used for tens of thousands of years (and where your cat’s biological instinct to bury waste stems from)! Furthermore, silica gel litter typically contains added chemicals and perfumes because its clumping and odor-absorbing capabilities are minimal compared to clay litter.
  • How much litter do I need?

    On average, you’ll need one 20-lb. bag of litter per cat every month. Every pet household is different, and litter usage will depend on how many cats you have, their size and waste habits, and what type of litter box they use.
  • How long does a bag of litter last?

    Typically, one 20-lb. bag of litter per cat will last one month. Our litter lasts longer than many other brands because our sun-dried clay is known for its superior ability to absorb liquids and clump quickly. This results in tighter clumps and less litter used. How long a bag of litter lasts also depends on how many cats you have, their size and waste habits, and what type of litter box they use. For example, a self-cleaning litter box like the Litter-Robot helps reduce litter usage by up to 50% as compared to scooping a traditional litter box.
