In a world where cat owners are increasingly seeking eco-friendly solutions, tofu-based cat litter is making waves as a game-changer. Gone are the days of dusty, heavy, and artificial-smelling litters – cat lovers are now turning to natural alternatives that are better for their homes, their cats, and the planet.
SOYSAND, a brand that has been redefining sustainable cat care since its launch in July 2024, quickly gained a devoted following, expanding into multiple states within months, thanks to its clean, lightweight, and highly absorbent formula. As someone who values both convenience and sustainability, I completely understand why tofu cat litter is a rising favorite – it offers superior odor control, easy clumping, and a dust-free experience that makes daily cleanup a breeze. Plus, it’s flushable and biodegradable, meaning you can care for your cat while reducing your environmental footprint.
With commitment to innovation, SOYSAND is proving that cat litter doesn’t have to be a messy or wasteful necessity. Instead, it can be a smart, sustainable choice that both cats and their humans love.
SOYSAND Tofu Cat Litter: The Future of Sustainable Cat Care
SOYSAND is more than just cat litter – it’s a commitment to sustainability, cat safety, and premium quality. Founded in Southern California, this innovative brand has been on a mission to revolutionize the cat industry with eco-friendly, plant-based solutions that both cats and their humans can feel good about. Since its launch in July 2024, SOYSAND has rapidly expanded, now available in eight stores and serving a growing community of over 700 happy customers. The demand speaks for itself – just one weekend saw an astonishing 2,200 pounds of SOYSAND litter sold, proving that cat owners are eager for a cleaner, greener alternative.
Unlike traditional clay or silica-based litters, SOYSAND’s tofu formula is dust-free, lightweight, and naturally absorbent, making cleanup easier and healthier for both cats and their owners. Its superior odor control locks in unpleasant smells, while its quick-clumping action means less waste and less mess. And because it’s biodegradable and flushable, it offers an environmentally responsible way to keep your cat’s space fresh and hygienic without contributing to landfill waste.
At its core, SOYSAND is all about combining convenience with conscious living. Every bag is crafted with the highest standards in mind, ensuring that cat owners don’t have to choose between performance and sustainability. As the brand continues to grow, its focus remains the same: providing a safe, effective, and earth-friendly solution for cat lovers everywhere.
Behind the Innovation: A Conversation with Kirk Iwasaki
Kirk Iwasaki, the founder of SOYSAND, shares how his background as a product designer and lifelong cat owner led him to create a smarter, cleaner, and more sustainable cat litter. In this exclusive interview, he reveals the challenges of breaking into the pet industry, why tofu litter outperforms traditional options, and what sets SOYSAND apart. With a commitment to eco-friendly innovation, affordability, and cat comfort, SOYSAND is changing the way cat owners think about litter.
What inspired you to start SOYSAND, and why did you choose tofu as the base material for your litter?
Kirk Iwasaki: I spent 15 years as a product designer and engineer and have always had an entrepreneurial itch. As a lifelong cat owner, I was always looking for new products to invent. In talks with friends and family about their pets, I would always find that conversations led to litter as being one of the worst parts of owning a cat.
Eventually, I heard about tofu cat litter, and after using it with my own cats, I found that it was almost perfect. I loved that it was dust-free and worked incredibly well in controlling odors. What I didn’t love was how hard it was to get my cat to use it, as well as scoop and sift. I set out to improve those issues and eventually found a way to do it! And that’s when SOYSAND was born.
What are the biggest benefits of tofu cat litter compared to traditional options like clay or silica?
Kirk Iwasaki: Tofu litter in general outperforms both clay and silica in key areas such as being eco-friendly and flushable. It is also low dust, making it healthier for both cats and humans. Unlike clay and silica, tofu litter is made from soy, which is not only highly absorbent but also naturally acidic. This acidity helps neutralize the ammonia in urine, which is basic, leading to better odor control. While tofu litter has a reputation for being expensive, customers should consider its value in terms of length of use rather than volume. Pound for pound, tofu litter lasts longer than clay and silica, meaning you don’t need to buy as much or as frequently.
What challenges did you face as a small business breaking into the pet industry, and how did you overcome them?
Kirk Iwasaki: The market is overflowing with litter options. These days, it seems like they’ve found a way to make litter out of anything – olive pits, walnut shells, coffee grounds, color-changing crystals – and many of these brands have much larger marketing budgets to promote their products. Luckily, the cat community is filled with really nice people who love talking about their pets and sharing their newest finds.
Word of mouth has been our best marketing tool so far. It has not only helped curb competition from less effective products but also promoted underdogs like SOYSAND, which actually deliver solid results. For us, the challenge has been about getting the word out – not just about SOYSAND, but tofu litter in general. Many people in the U.S. haven’t heard of tofu litter, so even just asking, “Have you heard of tofu cat litter?” is a great hook that opens the door for us to introduce SOYSAND.
SOYSAND has already achieved impressive success – what do you think sets your brand apart from competitors?
Kirk Iwasaki: As I mentioned earlier, tofu litter is an incredibly effective material, but until SOYSAND, the shape really held it back. Traditional tofu litter was hard to use, expensive, and often disliked by cats. We specifically focused on solving these issues by making SOYSAND the only tofu litter that is crushed to look and feel like traditional cat litter. This makes it comfortable for cats, easy to scoop, and compatible with automatic litter boxes. On top of that, we educate customers on how long SOYSAND lasts. Our testing has shown that 12 pounds of SOYSAND can last one cat and one litter box up to six weeks. With the right routine for indoor-only cats, your litter box can last for months without full replacement. When you compare the cost of litter over time, plus the added benefits, the sticker shock starts to make sense.
How does SOYSAND align with the growing demand for eco-friendly pet products?
Kirk Iwasaki: People want the best – for the planet, for their cats, and for themselves. Most other eco-friendly litters only excel in one or two of these areas. Some litters are highly sustainable and low-dust but fail at odor control, which is great for the planet and cats but not for humans. Others are eco-friendly and affordable but have an unpleasant texture that cats don’t like – good for the planet and humans, but not for cats. SOYSAND is different because it truly excels in all three areas. It’s sustainable and biodegradable, making it good for the planet. It’s low dust and has strong odor control, making it good for cats. And it’s easy to scoop and cost-effective over time, making it good for humans.
What’s next for SOYSAND? Are there any exciting developments, new products, or future plans you’d like to share?
Kirk Iwasaki: 2025 is going to be an interesting year. Tariffs and import costs will create some pricing challenges, but we are committed to maintaining our retail costs. Once we have more clarity on those issues, we hope to pursue eco-friendly packaging and different size offerings in the second half of the year. However, these plans will depend on how things unfold in the coming months.
