Our Top Pick: PetSafe ScoopFree Premium Crystal Non Clumping Cat Litter
Each bag of the PetSafe ScoopFree Premium Crystal Non Clumping Cat Litter may be specifically portioned out for refilling PetSafe’s reusable litter tray but that absolutely does not prohibit you from using it in whatever litter box you see fit. As crystals, you won’t need to maintain the two to three inches deep recommended for other cat litters, so this portion will still work perfectly for a single cat home. Each bag weights four and a half pounds and you’ll get two bags with each purchase.
This is a non-clumping litter that will track less and is 99% dust free, helping all those kitties with allergies. The crystals contained in these bags will absorb the urine and dry out any solid waste your cat leaves behind removing and eliminating odor, the manufacturer claims, up to five times more effectively than clay clumping litter.
With nearly 1,000 customer reviews on Amazon and an overall rating of 4.0 stars, it’s easy to see why it’s our top pick. Should you need more convincing, though, take a look at those reviews and be sold by the praises they sing.
PetSafe ScoopFree Premium Crystal Non Clumping Cat Litter Key Features:
- 2 scents available: lavender or original
- Sensitive formula available for softy paws
- Works with traditional littler box or PetSafe ScoopFree Reusable Litter Tray
Our Runner Up Pick: Fresh Step Crystals Premium Cat Litter
The Fresh Step Crystals Premium Cat Litter is listed as a two pack that will give you a total of sixteen pounds of cat litter. It’s a low dust formula, as most crystals are, and the eight pound bag will equate to a twenty eight pound bag of standard clumping clay litter, making it all the more efficient. But even besides the fact that the crystals are more efficient, they simply weigh less. So you can still fill your litter box up to two inches deep.
While you may get more or less time from the litter based on how many cats you have and how often they use the litter, the smell won’t be the determiner for when you replace the litter. It guarantees thirty days of odor control between replacement. The packaging suggests that for one cat, each bag will last two months, so with this $25 purchase, you’ll be set for four months. Not bad! Just remember to scoop and mix the crystals daily to keep the odor control working.
With just under 200 customer reviews on Amazon and an overall rating of 4.1 stars, it’s no wonder it made our list. With 75% of customers leaving it a glowing and positive review, there’s every reason to believe you’ll be one of the majority of satisfied customers.
Fresh Step Crystals, Premium Cat Litter Key Features:
- 2 – 8 lb bags included
- Subscribe and Save for bigger savings

Best Budget Pick: Ultra Pet Cat Litter Pearls Micro Crystals
The Ultra Pet Cat Litter Pearls Micro Crystals are so small that there are thousands of paths for liquid to flow and each path is lined with absorptive surfaces. For your cat’s solid waste, those thousands of particle surfaces will quickly dehydrate the waste and eliminate the odor. You’ll still want to scoop out the solids, but you’ll have to pay closer attention to the litter box because you won’t be able to tell it’s needed from the smell.
The litter is a low dust formula that will keep cats with sensitive lungs, allergies or asthma safe from attack. And when thinking about sensitive, consider the gentle feel your cat will have on his formula using the smaller and crystal particles rather than the larger, jagged rocks of clay litters.
While you can pick a 7 pound bag up for under $20, take a look at the Subscribe and Save option that will give you your cat’s litter box shipped for right around $15. That means not only will you be able to keep your cat stocked in an effective and gentle crystal litter for your cat – without ever needing to think about it again.

That means when you start noticing an odor, or the contents begin bothering you or your cat, you simply dump the entire thing, tray and all, into the garbage. Talk about a big time saver!
The crystals are 99% dust-free and low-tracking so you won’t have to worry about what your cat drags out of the tray after he does his business. The tray is meant to slip under the PetSafe ScoopFree Original Self-Cleaning Cat Litter Box, but even if you don’t have one of these, this tray will work slipped into any other litter box or just used on its own.

Who Should Buy Crystal Cat Litter
When you’re choosing which type of cat litter to purchase, you’re faced with two primary options: clay or crystal. You may be best suited for crystal cat litter if you have one cat because in most cases, you’ll only have to switch out the litter box once monthly. But even with more than one cat, you’ll notice a big extension of time between litter changing. Crystal litter will be a more hands-off experience for you as the cat parent. If you want as little involvement with your cat’s urine and feces as possible (and who doesn’t?) then a crystal cat litter may be just the thing for you.
You also may be interested in crystal cat litter if you don’t want to carry heavy objects (or aren’t able to for any reason) since clay litter is often in larger, heavier bags than crystal cat litter. A 30 day supply of clay cat litter will weigh more than twice as much as a 30 day supply in crystal cat litter. Because crystal litter is more efficient at odor and moisture absorption, you won’t have to pour it as thick in the litter box and the overall density of each individual particle is far less, too.
If you or your cat have asthma or other breathing problems, you might prefer crystal cat litter over clay as it doesn’t produce dust and is said to be better for these conditions.
Important Features To Consider
There are several important features to consider when purchasing crystal cat litter to ensure that you get the most bang for your buck. Here’s what to consider when selecting a crystal cat litter product for your cat:
- Odor control. The last thing that cat owners want to do is walk by their cat’s litter box and smell something funky. If you have a cat, you’ve definitely had this experience, and you want to look for crystal cat litter products that have amazing odor control. In many cases, products have additional scents to mask and overpower odors, but because the crystals are designed absorb so well, that technology alone will eliminate the vast majority of odors.
- Clumps well or clump-free and disposable. When you’re looking for crystal cat litters, you’ll notice that there are two types: clumping and non-clumping. When searching for clumping products, you want a cat litter that is easy to scoop and keep tidy. That means that the crystals aren’t getting caught on the bottom of the litter pan, making them frustrating to clean up. When searching for non-clumping products, the cat litter may also have disposable trays that can be thrown in the garbage, no problem.
- Dust control. It’s important to find a crystal cat litter that keeps dust at bay. Most will do this just strictly by the nature of their design. Crystal particles are far less likely to create dust, no matter how agitated the box or bag becomes, but if you’re concerned about it, make sure to look for a feature that says “dust free” or “low-dust.”
- Soft on paws. Your cat can’t tell you if walking on the clay litter is hard on his feet, but you may notice that he minimizes his time spent in the box. If he does his business and gets out in a hurry, that’s not necessarily a bad thing but you may find that the older he gets the less willing he is to put up with the paw discomfort. A soft silica crystal will be a walk in the park for him (figuratively – it’s far more gentle than an actual walk) and can help to ensure he keeps using his litter box.
- Cost. You will probably notice right away that crystal cat litter is quite a bit more expensive than clay cat litter. While that’s undeniably true, the cost differential can be a bit deceiving. Keep in mind that you shouldn’t compare price per pound as much as price for duration of the supply. When you compare 30 days of clay litter to 30 days of crystal litter, the price difference becomes less significant. You should also note that the crystal is far more convenient and will require less of your time. So, when you take into consideration what your time is worth, you may find that the cost difference is actually negligible.
- Durability. Cat owners prefer using crystal cat litter as it doesn’t need to be changed on a daily basis. Another important feature to look out for is durability. How long will the product last? Note the manufacturer’s recommended duration, but don’t stop there. If the majority of customer reviews say that a product can last for a few weeks (and the smell is still pleasant), that’s a good bet.
Frequently Asked Questions
What is crystal cat litter and how does it work?
Crystal cat litter is composed from silica gel. It’s highly liquid-absorbent and is generally said to absorb 40 percent of its weight. Because crystal cat litter absorbs liquid and dehydrates solid waste from your cat, it’s considered to be a great pick for cat owners who want this process to be as painless as possible.
If you’re used to emptying your cat’s litter box on a daily basis, you will notice a pleasant difference when you start using crystal cat litter. You will get rid of any waste and sift the cat litter around (which aids with the liquid absorption), but that’s it. You only need to switch the crystal cat litter once a month.
Is crystal cat litter better?
Whether or not it’s better is, of course, up to you. We can tell you it is definitely cleaner. For most homes, it’s also less work. If keeping your home neat and tidy is important to you, that would be certainly be motivation to purchase this product. Clay litter is known for being very dusty and in contrast, crystal cat litter is praised for being dust-free. Many cat owners consider crystal cat litter to be better than clay because of this fact. Crystal litter won’t track all over your house as commonly as a clay cat litter does, either, adding big to its column of pros. You may also prefer crystal cat litter since it’s bio-degradable and more environmentally friendly than clay litter.
Do cats like crystal cat litter?
Do cats ever do what you expect them to do? While many people say that cats prefer clay litter, many cat owners have found that their pets are very happy with crystal cat litter. Sometimes you’ll find they don’t care about the things you think they will. Other times you’ll have to make the call to use the litter that you like best, and try to get your cat on board. If your cat seems to be staying away from the litter box with the crystal cat litter in there, it’s possible that you need to purchase an unscented product and they will be much happier with that.
How often do you change crystal cat litter?
You don’t change crystal cat litter as frequently as clay litter. You can extend the life of the litter by removing solid wastes and stirring to activate more odor eliminating crystals. This ensure all crystals are used; that way you won’t be throwing away crystals that could still yet eliminate more odor. In fact, for most crystal cat litters, you only have to switch it out once a month. You’ll want to refer to the specific instructions from the manufacturer, but you can expect, with daily maintenance, you can extend the life and minimize your hand-on involvement in your cat’s urine and feces. And isn’t that just the best part?
