9 of the Best Crystal Cat Litters

Choosing the right litter brand for your kitty’s litter box matters more than you can imagine.

After all, cats have preferences for the type of substrate in their toilets, and not all of them are fans of clumping litter. (1)

Unlike traditional clay brands, crystals are better at minimizing odors, and they’re easier to scoop from the bottom of the box.  

And as specialists from PetMD explain, “They tend to produce less dust than clay litters.” (2) So, crystals are better for people and animals with allergies.

But what are the best crystal litter brands? Let’s see my 9 suggestions.

How to Choose the Best Crystal Litter for Cats?

As you can see, you’ve got plenty of options to choose from when it comes to silica gel brands. So, let’s talk about what you should consider when shopping for the best crystal litter for cats.

#1 Crystal size

Cats have texture preferences when it comes to using the toilet box. Tiny crystals are better for cats with sensitive paws because they’re less uncomfortable to dig.

On the other hand, larger crystals are better if you’re worried about your cat ingesting the particles because they don’t stick to the fur as small ones.

#2 Scent

Usually, unscented litter is better than scented one. Not all cats like the pungent odor of scented brands, and they can be put off using the toilet box.

Moreover, scented products don’t always mask the odors from the toilet box. In fact, they can make the unpleasant smell worse. 

#3 Number of cats

Crystals last longer than traditional clay brands, but they’re more expensive. Usually, one bag is enough for a single cat.

You should consider how many cats and toilet boxes you have to determine how much silica gel granules will cost per month. 

#4 Odor Control

Most crystal brands have excellent odor control, but they differ in how many days they trap unpleasant smells.

#5 Dust

In general, crystals are less dusty than bentonite clay, but not all crystal brands are low-dust. Keep that in mind if your pet has allergies.  


Final Recommendation & Conclusion

Crystal cat litter products are great for reducing unpleasant cat toilet odors and preventing litter from sticking to the bottom of the box.

Moreover, crystal litter isn’t as dangerous as clay when ingested because the crystals won’t swell in the stomach. And crystals last longer than clay, making them perfect if you want to save money.

Of all the different kinds of cat litter I’ve reviewed, PetSafe ScoopFree Crystals are the best, thanks to their absorbency, low-dust formula, and superior odor control.

And it’s the best crystal cat litter for automatic litter boxes, such as ScoopFree and Litter Maid.
