One of the biggest questions people ask before buying a self-cleaning litter box is surprisingly simple: Will I have to switch my cat’s litter?
After all, cats can be creatures of habit. If you’ve finally found a litter that controls odor, clumps well, and doesn’t send your cat running in protest, the last thing you want is to start over.
The good news is that the homerunPET CS106 is compatible with a wide range of popular litter types. Whether you prefer traditional clumping clay or you’re interested in trying newer plant-based options like tofu or cassava litter, the CS106 is designed to handle them. Its two interchangeable litter filters are what make that flexibility possible, allowing you to match the filter to the size of your litter granules for more efficient sifting.
The HomerunPET CS106 is one of the largest automatic litter boxes I’ve tested, with a roomy 106L dome and oversized 12L waste bin. Designed for big cats and real multi-cat homes, it also features an auto-refill system, ultra-quiet operation, and strong safety sensors. If you want a more hands-off litter setup, this one delivers.

Let’s take a closer look at which litters work best and how to choose the right one for your cat.
Why Litter Compatibility Matters
Every self-cleaning litter box works by separating clean litter from waste after your cat finishes using it. That sounds simple enough, but the process depends on the litter itself.
Different litters vary in particle size, weight, and how firmly they clump. If the litter is too small, too large, or doesn’t form solid clumps, it can affect how well the cleaning cycle works. In some cases, clean litter may get discarded along with waste, or small pieces may fall through the filter when they shouldn’t.
That’s why choosing a compatible litter is just as important as choosing the litter box itself.
What Types of Cat Litter Work with the homerunPET CS106?
The homerunPET CS106 supports quite a few of the most popular clumping litters. It comes with two interchangeable litter filters with different hole sizes, making it easy to accommodate both larger and smaller litter particles.
Clumping Clay Litter
Clumping clay is the most popular choice for many cat owners, and for good reason. It creates firm clumps quickly, controls odors well, and is available pretty much everywhere from your favorite pet store to the grocery store.
Since it’s what many cats grow up using, it’s also a great option if you’re introducing your cat to an automatic litter box for the first time. If you’re happy with your current clumping clay litter, you can almost definitely continue using it with the CS106.
I say “almost definitely” just in case there is some weird random super-specialty litter out there that I haven’t heard of yet that’s an exception. I don’t do absolutes unless I’m absolutely sure. 😀
Fresh Step Extreme Clumping Cat Litter is formulated with the power of Febreze in Mountain Spring scent to destroy extreme litter box odors. This 99.9% dust free litter formula with Ammonia Block Technology, controls the growth of bacterial odors and blocks urine odors, as it leaves behind a Mountain Spring scent. The paw activated fragrance releases every time your cat uses the litter box, providing odor control as needed without being overpowering.
Tofu Cat Litter
Tofu litter has become increasingly popular over the last few years, especially with cat owners looking for a more natural alternative to clay.
Made mostly from soybean byproducts, tofu litter is lightweight, highly absorbent, and generally produces very little dust. Many brands are also biodegradable, and some can even be flushed in small amounts (although it’s always best to follow your local plumbing guidelines and the manufacturer’s recommendations. Even then, I wouldn’t flush it if you have a septic system.).
One feature that helps set the homerunPET CS106 apart is its ability to work with tofu litter. Thanks to the included smaller-hole litter filter, it can effectively sift the smaller granules that tofu litter typically uses.
That’s something not every automatic litter box offers. For example, the Litter-Robot isn’t designed for tofu litter, making the CS106 a perfect option for those who already use it or have been thinking about making the switch.
An ultra low tracking, clumping, dust-free tofu cat litter that disintegrates completely in water so that you can flush safely down the toilet. Totally mess-free. Flushable, odor eliminating, quick clumping and low-tracking for a squeaky clean home. Thoughtful, non-toxic ingredients made from soybean byproduct (tofu) that would have otherwise gone to the landfill – safer for your cat, better for the planet. Gone are days of lugging litter all the way home. We get you what you need, when you need it. Includes free shipping.
Cassava Cat Litter
I’ll admit it, before researching automatic litter boxes, I had never even heard of cassava cat litter, and I’ve lived with cats for more than 30 years.
Cassava is a tropical root vegetable that’s grown throughout many parts of the world. If you’ve ever eaten tapioca pudding, you’ve actually had cassava. Tapioca starch comes from the cassava root.
Manufacturers use processed cassava starch to create a natural, biodegradable cat litter that clumps surprisingly well. It’s typically low in dust, lightweight, and designed to absorb moisture quickly.
For cat owners who want a plant-based litter without sacrificing clumping performance, cassava has become an increasingly popular option. The homerunPET CS106 is compatible with cassava litter when paired with the appropriate filter.
This premium litter features a unique blend of large and small grains for quick and easy clumping, making clean-up a breeze for pet parents. The excellent odor control and dust-free formula keep your home fresh and clean, while the all-natural cassava composition provides a safe and eco-friendly solution for you and your pet.
Cassava-Tofu Blend
Some litter brands combine cassava and tofu to create a litter that offers some of the best qualities of both materials.
These blends often provide strong clumping, excellent odor control, low dust, and a lightweight feel. They can also be a nice middle ground for cat owners who want to transition away from clay litter without making a dramatic change all at once.
Since particle sizes can vary between brands, having two litter filters gives the CS106 the flexibility to accommodate these blended formulas.
Made with thoughtfully selected plant-based ingredients, including tofu, cassava, and recycled coffee grounds, this formula delivers effective odor control and fast clumping for easy daily maintenance. It creates firm clumps that scoop cleanly to help reduce waste, keep the litter box fresher between cleanings.
Tofu-Bentonite Blend
Another increasingly common option is a blend of tofu and bentonite clay.
These formulas combine the lighter weight and lower dust of tofu with the strong, reliable clumping performance that bentonite clay is known for. Many cat owners find they offer an excellent balance between natural ingredients and traditional litter performance.
Like the other compatible litter types, these blends work well with the homerunPET CS106 when paired with the correct litter filter.
Made from natural bean husks and bentonite clay, this litter quickly absorbs moisture and forms clumps for easy scooping. Plus, its long-lasting odor control formula traps and reduces unpleasant smells, replacing them with a pleasant lily scent that’s released upon contact with cat pee.
How the Two Litter Filters Make the Difference
The real secret behind the CS106’s versatility is its pair of interchangeable litter filters.
Instead of using a one-size-fits-all approach, homerunPET includes filters with different hole sizes so you can match them to your preferred litter.
Using the appropriate filter helps:
- Separate waste from clean litter more efficiently
- Reduce the amount of clean litter that’s accidentally discarded
- Support both larger and smaller litter granules
- Make it easier to switch litter types in the future if your needs change
It’s a simple feature, but one that gives cat owners far more flexibility than many self-cleaning litter boxes offer.
Which Litters Should You Avoid?
While the CS106 works with nearly all clumping litter varieties, not every litter is a good fit for an automatic litter box.
In general, you’ll want to avoid non-clumping litters or anything with extra-large pellets that are too big to pass through the filter. For the latter, I’m thinking some (not all) walnut-based or pine-based litters that have the really huge pellets.
Choosing the Best Litter for Your Cat
The “best” litter really depends on what matters most to you and your cat.
- If odor control is your biggest priority, a quality clumping clay litter is still hard to beat.
- If you’re looking for a low-dust, plant-based alternative, tofu litter is an excellent choice, especially since the CS106 is designed to support it.
- For eco-conscious households, both cassava and tofu litters offer biodegradable alternatives to traditional clay.
- And if you’re not quite ready to leave clay behind completely, blended formulas can provide a nice compromise.
The flexibility to choose the litter that works best for your home is one of the biggest advantages of the homerunPET CS106.
