In today’s homes, pet care products are expected to do more than serve a basic function. They’re part of a larger lifestyle—one that values cleanliness, efficiency, and thoughtful design. Petkinns, a U.S.-founded brand, enters this space with a clear focus: improving everyday routines through practical innovation. Its flagship product, SOYSAND™ tofu cat litter, reflects that philosophy by rethinking one of the most routine aspects of cat ownership.
A Brand Built on Practical Innovation
Petkinns was founded in 2024 by Kirk Iwasaki and Lucas Tang, two engineers with complementary expertise in product design, manufacturing, and supply chain operations. Their shared goal was not to reinvent routines entirely, but to refine them—creating products that improve how people live without requiring them to change established habits.
This mindset shapes the brand’s direction. Rather than introducing overly complex systems or niche alternatives in exchange for innovation, Petkinns focuses on designing new solutions that integrate easily into everyday life. The result is a product philosophy centered on simplicity, familiarity, and functional improvement.
The Everyday Challenge of Cat Litter
Cat litter is one of the most routine—and often dreaded—parts of cat ownership. For many households, it’s a daily touchpoint that directly impacts cleanliness and comfort within the home. While traditional clay litter has remained widely used for decades, it also comes with common concerns such as dust, tracking, odor management, and not being eco-friendly.
At the same time, alternative litters made from materials like corn or grass have introduced new options, but often require adjustments in how they are used or how cats respond to them. This balance between familiarity and innovation is where SOYSAND™ positions itself.
A Familiar Feel, Reimagined
SOYSAND™ is designed to closely resemble traditional clay litter in both appearance and texture. Its small, crushed granules are intended to feel familiar to cats, which may help support a smoother transition for households that are used to clay-based products.
This design choice reflects a key principle behind the product: innovation should not come at the cost of usability. By maintaining a familiar look and behavior, SOYSAND™ aims to function as a seamless upgrade rather than a disruptive replacement.
Material Choice and Composition
Where SOYSAND™ differs from traditional litter, is in its material. The litter is made from the byproduct of food-grade tofu production, offering a plant-based option that is sustainable and biodegradable. This approach aligns with a broader interest in more eco-friendly household products, while still maintaining the high performance standards expected from a daily-use item.
The use of soy-based material also contributes to the product’s absorbent properties. Soy is naturally capable of absorbing moisture efficiently, which plays a role in how the litter manages liquid, forms clumps, and naturally neutralize odors.
Clumping, Odor, and Maintenance
Functionality remains central to SOYSAND™’s design. When exposed to liquid, the litter forms firm clumps that hold together when scooping, even if it’s days later. This can make routine cleaning more efficient and help maintain the overall freshness of the litter box.
Odor management is another important consideration. The natural properties of soy, including its absorbency and slightly acidic nature, help address ammonia-related odors commonly associated with cat urine. While results may vary depending on usage and environment, odor control naturally happens due to the raw materials, without the need for additional chemicals, or overpowering scents to mask it.
Additionally, SOYSAND™ is created to be virtually dust free and low tracking. These factors are often cited as concerns with traditional clay litter, particularly in households that prioritize a clean and comfortable indoor space.
Designed for Real Homes
One of the defining characteristics of SOYSAND™ is its compatibility with existing litter boxes and routines. It does not require specialized equipment or a change in daily habits, making it easily accessible for a wide range of cat owners.
The product is available in both Oatmeal Scent and Unscented options, as well as different bag sizes, allowing households to choose what best fits their preferences. This flexibility supports a variety of living situations, from smaller apartments to larger, multi-cat homes.
Looking Ahead for Petkinns
SOYSAND™ is the first product in what Petkinns envisions as a broader lineup of pet care solutions. The company plans to continue developing products that bring the same level of thoughtful design and ease of use to other aspects of pet ownership, beyond just cats.
By focusing on incremental but meaningful improvements, Petkinns is positioning itself within a category that values innovation and requires practicality.
A Thoughtful Shift in Everyday Pet Care
As consumer expectations continue to evolve, products like SOYSAND™ highlight a shift toward solutions that balance performance with simplicity. Rather than asking users to adapt, Petkinns emphasizes meeting people where they are—offering products that align with existing routines while introducing updated materials and design considerations.
For modern households seeking a cleaner and more streamlined approach to pet care, SOYSAND™ represents a practical step forward in how everyday essentials can be thoughtfully refined.
