Top 5 Crystal Cat Litters at a Glance

1. Fresh Step Premium Crystals Clumping Cat Litter – My Top Pick

Premium Crystals by Fresh Step absorb 5x more moisture than clay cat litter and because these crystals are small, they create very minimal dust, if any.

Because of the quality in absorption, it will lock in odors much faster.

This is a clumping cat litter which makes it super easy to scoop out your cats pee and poop as and wehn they do their business. This is what makes clumping litter so good because it doesnt effect the remaining litter in the tray, so the litter will last longer.

It’s lightweight and easy to scoop and easier to clean than other litters. Fresh Step recommend filling the litter box with at least 1.5 inches of this crystal litter. This gives your cat enough to cover things up.

Premium Crystals should be changed once a month if you have one cat and little more often if you have more than one, 10 to 15 days would be ideal.

Overall, this is a premium quality silica gel litter that many customers swear by.

2. Ultra Pet Cat Litter Pearls – Runner Up

Ultra Pet Cat Litter Pearls is one bag of silica crystals designed for one cat that will last for one month.

It dries solid waste and absorbs cat urine very efficiently providing excellent odor control and making it easy for you to scoop out.

A poop and urine free litter is best for both your cat and the household environment so you want a crystal litter that makes it as easy as possible to clear up everyday and Ultra Pet does a great job at this.

This is a 5lbs bag which should last one cat for an entire month. It’s unscented which means it won’t put your cat off from using it if they are not used to fragrented litter.

Because of the way crystal litter acts, it is 99.9% dust free. It’s also has very low tracking so your cat won’t traipse it around your home.

It’s ideal for cats with sensitive paws or who are prone to allergies. It can be used for all cats and kittens.

Ultra Pearls Cat Litter ,5 lbs
  • Elimates Odors - Maximum Odor Control
  • Soft on Cat's Paws
  • Absorptive surface with 1000's of mini-channels for liquid waste absorption
  • Dries solid waste for odor control
  • Very Low Dust

3. Just the Crystals Premium Crystal Cat Litter

Coming in at number 3 on our list is this one from the brand Just the Crystals. This one is sold in two 4.4 lb bags. Unlike the one above, this one has no scent and is fragrance free.

Like many of the crystal style litters, this one is recommended by buyers, as it is very low on dust. Generally speaking these type of litters last for up to 5 times longer than the clay based litters.

The manufacturer claims these have the highest rated absorbency of any crystal litter on the market.They don’t use any fragrances to cover odors. Buyers did say that these were better than having a chemical “masking” fragrance in their home.

Around 2/3 of buyers give these the full 5 star review treatment, and the number of complaints about these are very low. Those are both good signs, and make these worth your consideration.

4. PetSafe ScoopFree Premium Crystal Non Clumping Cat Litter

This one works with the ScoopFree litter tray and also as a stand alone litter. Please note that this is a non clumping litter.

In terms of fragrance you actually have three choices which are sensitive, original scent and a really nice lavender. With this one you get 2 x 4.4 lb bags, and this one is good value for money. Like most of the crystal litters this one is almost completely dust free, and good at preventing tracking.

Buyers advise keeping this litter away from areas of high humidity, such as bathrooms and basements. The same really applies for any cat litter. It is all designed to absorb moisture and it will do that. Too much moisture which is not cat urine will mean you have to replace it more often.

  • Buyers like the fact that this is a lightweight litter and that makes a big difference for them
  • They also really liked the fact that it controlled odors really well
  • The only real complaint I could find was that a few buyers thought that a couple of the packs they received were more dusty than previous supplies
  • A small minority also thought that the fragrance didn’t last long enough

5. Ultra Pet Ultra Cat Litter

This one comes in two slightly different formats of crystals. Those are micro crystals or micro pearls. The crystals are pretty much in the same vein as the others that I have described.

The pearls on the other hand are a different type altogether. These are designed to be gentler on the cat’s paws and that makes them ideal for small kittens, or for older cats. The “pearl” type are however more expensive.

  • Buyers said that these were good for drying out cat poop waste
  • They were very good with odor control and also with reducing tracking
  • Most buyers said that with one cat, these lasted about a month
  • The biggest complaint (around 10% of buyers) was that these were too dusty.

6. UltraPet Tracks-less Litter Pearls

Last but not least on our list is another option from UltraPet. These were a low rating at one time, but with more buyer reviews available they have started to get better, and currently they get an average buyer satisfaction rate of around 68%.

This comes in a 3.5 lb bag and have been designed to last for one month with one cat.

As the name would suggest these are designed to do the normal things that a litter should like control odors, and be light and easy to use. What makes this one slightly different is that the crystals are shaped as semi-spherical and that is meant to reduce tracking of litter around your home.

These again really do split opinion right down the middle. They are one of the lowest rated on our list.

Things to Consider When Choosing a Crystal Cat Litter

Why Buy Silica Gel Crystal Cat Litter?

With so many different types of cat litter on the market, why would any cat owner consider buying one that is made from crystals of silica gel? It is a very good question, and the reality is that more and more owners are buying these, rather than the standard clay based litters.

There are a lot of very good reasons to consider making the switch, and I have listed both the advantages and disadvantages down below.

I have also added an article which you may find useful about exactly how to use a silica gel litter, and you can read that by clicking here.

Easy To Use

There is no doubt that silica gel cat litter is the easiest of all the cat litters to use. In essence all you need to do is remove the poop once or twice a day, and give the litter a stir. That is all there is to it until you need to do a full change out of the litter.

Now the time between changes depending on the brand that you buy and also on the number of cats that you have. All of them last much longer than other litter types, so less cleaning up to do.

Cleaner to Use and Low on Dust

In principle, these are sold as they are a lot cleaner to use than many of the clay or natural style of cat litters available on the market place. Over the years I have used many types of litter. I have yet to find one that is 100% dust free.

The one thing that I can tell you is that any silica gel will be less dusty than any clay litter.

Lighter to Handle

These lightly made up crystals are a great deal lighter than either a clay litter, or all of the natural or biodegradable litters. That in itself does not sound that important.

However, if you have ever carried around a heavy bag of litter, then by changing to crystals, you will never have that problem again.

Likewise when it comes to scooping these are a lot easier to mix. It is also considerably easier to fill and empty a litter box.

Excellent at Strong Odor Control

Most of these small crystals can absorb up to 15 times their own weight. Not only do they absorb well, but they also capture any germs and bacteria, and lock those inside the tiny spores on each individual crystal.

Better for the Environment

Now all of these crystal litters still have to go into your main waste. However as they are smaller and lighter a lot less will end up in land fill sites, simply as they are much smaller, but last longer than many of the clay or biodegradable litters.

There is 70% less landfill required with these types of litters.

Disadvantages of Silica Gel Crystal Litters

Like most products this litter type also has some disadvantages, and I like to include all the information on my reviews. That way you can make your own mind up, which type is best suited to your own individual circumstances.

Expensive to Buy

When you compare these dollar for dollar against weight, these crystals are about 3 times more expensive than a clumping clay litter. That may initially put you right off buying these, but there is more to it than just the price.

These also last much longer, up to 2-3 times longer, so you will not have to buy these so often. The recommendation for changing litter types is as follows:

  • Non-clumping – weekly
  • Clumping – every 2 weeks
  • Natural or Biodegradable – weekly
  • Gel crystals 4-6 weeks

So if you strictly follow the recommended litter change periods, silica gel crystals do hold their own in terms of price. They are slightly more expensive though, and a lot of that comes down to regular daily cleaning of the litter.

Can Be Messy even Unhygienic

These are really not suitable for an open litter, as if your cat is a digger and moves its cat litter around, these will end up all over the floor. These are circular ball type of crystals and they will go everywhere, so can be quite messy.

Any spills can be hard to clean up, given the nature and size of these smaller crystals.

There is an argument that when a cat poops on these crystals, that when the poop is removed, some may remain on the crystals. Mixing that in is clearly not a good idea, but some people do that. It is a good idea to scoop out some of the crystals around the area where your cat has pooped.

Only Suitable for Some Automatic Litter Boxes

If you have a self-cleaning litter box, you will need to check that it’s suitable for silica crystal litters as some of these types of litter boxes require natural clumping or clay cluping cat litters.

Conclusion

Overall, silica crystal litters are generally more expensive that other types of cat litter. But if you’re looking for ease of use, great odor control and something environmentally friendly then a silica based cat litter might be the best choice for you.
