About Us
Why We Started
It all began with one cat in a grey coat.
Her name was TT.
At the age of nine, TT was diagnosed with stage 2 kidney disease.
The vet said the disease was manageable—but irreversible.
Average prognosis: three years.
But as her guardian, I couldn’t just accept that.
Not without trying.
So I searched. I read. I reached out to experts.
That journey led me to AIM—a protein involved in the body’s internal waste-clearing system.
I was able to get into contact with Dr. Toru Miyazaki, the scientist who discovered AIM.
With his help, TT became the first cat to receive AIM-focused nutritional support.
And to our surprise, her condition stabilized.
She didn’t just survive—she stayed in stage 2 for six more years.
Her energy returned, and her appetite came back.
That’s when I knew:
This wasn’t just for TT.
Other cats could benefit too.
When Waiting Wasn’t an Option
Drug development can take over a decade.
But cats with kidney stress can’t wait that long.
Neither could TT.
We chose a different approach.
Supplement-based care, built on urgent need and guided by science.
An informed and intentional choice for cats, rooted in real-world cases.
From One Cat to a Shared Mission
To expand this approach, I sought insight from experts.
Dr. Kobayashi Motoo, a Japanese veterinarian focused on phytochemical support for aging cats.
Dr. Kim Jae-young, a leading feline clinician in Korea with experience in kidney care and stem cell therapy.
Together, we refined our formulas, blending scientific insight with practical clinical experience.
What started with one cat is now a growing team—working with veterinary experts across Japan and Korea to support the cats that need more than routine care.
What We've Done So Far
In 2024, we launched Greycoat Research.
Since then, we’ve since provided over 1,300 personalized consultations to guardians with cats facing kidney-related challenges.
Among them, 97% reported noticeable improvements in their cat’s condition—in energy, appetite, and lab stability.
But the message that stays with us the most is this:
“Thanks to you, my cat is still with me.”
Those words remind us why we started—and why we can’t stop.
We’re Still Running
Greycoat Research wasn’t created as a business plan.
It was born from the combined efforts of multiple people to save one cat.
We’re here for the guardians who still believe there’s something they can do.
For the cats who aren’t done yet.
For the moments that shouldn’t be taken away too soon.
We don’t promise outcomes.
But we can offer everything we’ve learned. and everything we still believe in.
From one grey coat to over 1,300 cats and counting—we’re still running.
