While there aren’t as many silica cat litters on the market as traditional clay, that doesn’t make this material any worse of a choice for your beloved cat. Silica cat litters work differently than clay, wood, paper and typical cat litters, and that leaves this type of litter often misunderstood.

In this article, not only do we break down the benefits of using silica kitty litter, but we discuss how the crystal granules work to control odor and absorb liquid. We also talk about key components to look for when choosing the best silica cat litter for your fancy felines. Most importantly, we share our top six silica cat litter recommendations.

5 Benefits of Using a Crystal (Silica) Cat Litter

Although silica gel cat litters aren’t as common as some of the other leading cat litter materials, they can have similar traits. Certain benefits may also be similar to those of mainstream litter options, but silica cat litter has a few of their own.

  1. Good for respiratory health: Silica ball cat litters won’t cause airborne clouds when your cat is sifting through their litter, or when you’re pouring it for replenishment. Silica litters are typically dust free, which will help keep your entire household healthier. No more inhaling fragrances and perfumes.
  2. Gentle on your cat’s paws: Silica gel cat litter is often soft and fine, making it gentle on your cat’s paws. This is a great benefit for kittens, senior cats, post-surgical cats and kitties who have sensitive paws.
  3. Can be reused longer: Moisture evaporates from silica litter or is absorbs via pores, which means you can reuse it for a longer period of time than traditional clay litter. This helps keep excess litter out of landfills.
  4. Excellent odor control: Silica litter is known to absorb and eliminate odor better than some of the more common cat litter types.
  5. Non-toxic: Most kitty cat litters are non-toxic, a wonderful benefit for the environment and your cat’s health. Some silica ball cat litters are even biodegradable!

Since silica gel litters for cats are different that standard, more common cat litters, below we explain how they work.

How Silica Cat Litters Work

Many silica cat litter brands suggest that there is no scooping of urine needed after your cat uses their litter box. But why? Where does the urine go if there’s no clumping properties? Silica gel granules consist of tiny pores than we cannot see at a glance. These pores absorb moisture and urine that the granules come in contact with. After your kitty makes a pit stop at their box to urinate, simply stir up the litter. This will help the silica gel litter adsorb all of the liquid. When maintained properly, the urine will not reach the bottom of the litter box.

Another important fact to note is that silica get and crystalline silica are two completely different materials. Silica gel is safe for cats, while crystalline silica is not. Silica gel and crystalline silica are comprised of different minerals. Crystalline silica is not present in silica gel cat litters, so you do not need to worry about the risk.

5 Components to Look for in a Good Silica Cat Litter

Here are some factors to consider when purchasing the best silica cat litter for your kitties:

  1. Particle size: A good silica litter will have small or tiny granules. Large granules can potentially be uncomfortable for your cat’s paws. Another benefit to using a silica litter with small granules is it can be used in sifting and mechanical litter boxes. However, larger particles will be better for cats with long hair because they won’t easily get stuck in their fur.
  2. Eco-friendly: Not all silica gel cat litters are biodegradable, but some are! If you want to do your part in helping the environment, we suggest choosing a silica crystal litter that specifically states it is biodegradable. Remember to check the labeling!
  3. Infused with herbs: For cats who are struggling to use the litter box due to stress or behavior, you may consider purchasing a silica litter for cats that is infused with natural essences. These herbs will attract your cat to the litter box and help reduce stress.
  4. Weight of the litter: Most silica kitty litters are lightweight. Using a lightweight litter is beneficial because it’s easy to carry, pour and dispose of.
  5. Clumping: Silica cat litters are available in clumping and non-clumping options. What you choose strictly comes down to preference. It’s important to note, however, that a majority of crystal cat litters are non-clumping due to the way the granules work.

Next up we outline our six silica cat litter recommendations.
