  • Biodegradable and non-toxic – Cat litter with silica gel is more environmentally friendly because it’s biodegradable and non-toxic, which is also an excellent benefit for you and your cat.
  • Minimal dust – Crystal cat litter is virtually dust-free and is, therefore, preferable in many households, particularly ones that have members with allergies.
  • Odor neutralizing – The quartz sand composition of the silica-based cat litter and its unique atom structure allow the silicon to bind with a high amount of liquid and neutralize any odors.
  • Easy to maintain – Silica cat litter needs to be changed by emptying the entire box once a month and replacing it with new litter. Since it doesn’t clump, all you have to do meanwhile is scoop the solid waste.
  • Better capacity – One of the most impressive features of this product is that five liters of silica kitty litter equal roughly three times the amount of clumping litter. Silicon cat litter usually lasts up to four weeks before it needs to be changed.
  • Lightweight – Silica-based cat litter is significantly lighter than traditional clay litter, and its weight increases with liquid absorption.

How is Silica Cat Litter Made

Up until the 1950s, cat parents filled their cats’ litter boxes with sand, dirt, or ashes, which is something someone living in today’s modern world probably wouldn’t even want to imagine. Just picture your kitty walking around the house after having just taken care of their business and leaving dirt or ash track marks all over the place.

Horrified at the image?

How about feeling your kitty’s warm body and their soothing, healing purring vibrations while you are asleep and then jumping up startled at the realization sand or dirt from the litter box is accompanying your feline companion in the bed with you?

So much for your comfort and peace.

The introduction of clay cat litters made cat parents sigh with relief, and an even bigger wave of relief swept up the nation when clumping cat litters hit the market.

Finally, silica cat litter made its breakthrough and introduced its crystal formula, making things even easier for cat parents.

Silica-based cat litter manufacturers use silica gel to make the crystals responsible for its improved odor control. They manufacture this type of cat litter from sodium silicate sand (quartz sand) processed with water and oxygen.

The result is a kitty litter containing beads called silica gel crystals, or microcrystals, with tiny pores all over them. The pores allow the crystals’ absorption of kitty urine and then promote their ability to let the absorbed liquid evaporate.

There is fear present among some cat owners regarding the possibility of their cat ingesting these super absorbent beads as they lick their paws and groom themselves after visiting the litter box. The fear associated with this comes from silica’s connection to respiratory issues in both humans and felines.

Not to worry, though, because many silica cat litter manufacturers assure cat lovers that they specifically formulate the silica gel crystals in such a way that there is no compromise when it comes to your safety and the safety of your cat. The beads don’t contain any crystalline silicate, a harmful mineral found in the earth’s crust.

Frequently Asked Questions

  1. Are silica-based cat litters flushable? No. Just as you wouldn’t flush any other cat litter, you should never flush crystal cat litter either. If flushed down the toilet, it may cause even bigger issues and clogs compared to other litters because its moisture absorbency will make it expand and create major plumbing problems.
  2. Can I mix crystal cat litter with traditional clumping clay litters? We don’t recommend mixing these different products regularly. You may mix the kind of litter your feline is used to with the new kind you are introducing to help them adjust faster when you first introduce the transition to using silica cat litter. Leave the old kind at the bottom of the litter box and cover with the new one. It would be best if you didn’t do this for a long time, though. Cats will usually be fine with the new litter after the first use of a mixed litter box. Many cats take to the silica cat litter immediately.
  3. Can bacteria grow in my cat’s litter box if I use silica cat litter? No. Because of its crystals that absorb urine and dehydrate feces, silicon cat litter renders your feline’s litter box not only free of bacteria but also makes it impossible for bacteria to grow inside it.


Choosing the best silica cat litter for your feline doesn’t have to be stressful. There are excellent crystal cat litter options on the market, and your kitty will thank you for taking the time to explore them.

Of course, you should always take the necessary precautions when handling kitty litter—silica-based litter or any other kind—and thoroughly wash your hands after. If you are pregnant or have a weaker immune system, hand off the task to another member of your household.

We hope now that you’ve read this article, you can see the numerous advantages silica cat litter has over any traditional clay cat litters out there. We urge you to consider transitioning your cat baby to this outstanding product that has revolutionized the litter-box experience for cat lovers and their felines worldwide.
