The Best Crystal Cat Litter

Though clay used to be the more popular choice, many cat owners are now switching to crystal litter for one major reason: it can absorb liquids much better than clay. That is because it has sodium silicate sand in it which increases the absorbency. Cat owners love this litter’s ability to soak up liquids because it helps to keep the smells of a litter box less potent. It's also a dust-free litter, so those with allergies are happy to make the switch. And if you’ve ever been around a litter box, you know that is a major bonus. Here are the best crystal cat litters on the market.

Frequently Asked Questions

Is crystal cat litter good for cats?

Because most crystal cat litter is made with silica crystal beads, it is generally safer for cats and people, especially those that are irritated by the dust from traditional litter. The crystal litter also helps with neutralizing odors which is a benefit for you and your cat as well.

Do you scoop crystal litter?

Crystal cat litter is usually made from silica gel. That silica gel absorbs liquid waste so that it is easier for you to clean up. The silica gel clumps up when wet, allowing you to scoop it up out of the litter box without having to dump the entire box.

How often should I change my crystal cat litter?

Depending on the quality of the crystal litter that you choose and the amount of mess your cat makes, you should only need to replace the entire box of litter about once every month or so. When you remove clumps out in between a full replacement, you may find you need to add a little more litter to the box.
