AIM-Based Kidney Support for Cats
Developed with Dr. Toru Miyazaki, the scientist who discovered AIM— a key molecule in how cats clear kidney waste.
Over 10,000 bottles trusted—now available in the U.S. and worldwide.
What Makes It Different
Cats process waste differently than other animals—
because their AIM stays inactive.
This unique trait was first identified in a 2016 study published in Scientific Reports
(title: “Impact of feline AIM on the susceptibility of cats to renal disease”, by Dr. Toru Miyazaki).
This formula was created to support that feline-specific biology—making it one of the few kidney supplements truly made for cats.
It All Started with One Cat—TT
Claire, TT’s guardian, collaborated with Dr. Toru Miyazaki—
the scientist behind AIM research—
to explore new ways to support her cat TT’s kidney health.
Guided by Dr. Miyazaki’s research and insights,
they developed a specialized formula designed to help maintain kidney balance over time.
This approach became the foundation of the Dr. Toru Protocol. Inspired by one cat’s journey, now trusted by thousands.

What Guardians Are Saying
Customer Reviews
I've been giving my cat Protocol for almost 2 weeks. Maybe after she's had her labs done, I can say if Protocol has made a difference. However, her energy level seems good & she takes Procol well in her food.
Our cat Apollo is FeLV+ and, as a result, developed renal pelvis dilation, which led to chronic kidney disease (CKD), stage 2. Before starting treatment with GreyCoat Research products, his blood tests showed urea levels at 113 mg/dL and creatinine at 2.3 mg/dL. He also often experienced anemia, as his kidneys are impaired in producing the hormone that stimulates red blood cell production.
After almost two months of using the Dr. Toru Protocol and the Intensive Protocol, with one capsule daily, we’ve already noticed significant improvements in his energy levels. He’s much more active, climbs (which he never did before), and his blood tests have shown positive changes! While his creatinine levels haven’t decreased yet, his urea has dropped to 94.3 mg/dL, and, most surprisingly, he is no longer anemic - for the first time in two years!
We plan to continue the treatment and run new tests next month to monitor his progress. We are so grateful to have found GreyCoat Research! Congratulations on developing such effective products, and thank you for the online support!
Best regards,

Moosya and her CDK stage 3
Moosya is 19. In November 2024 she was diagnosed with CKD stage 3. She lost weight, appetite and her hair around the neck was falling out. The vet said to think about euthanasia. I started searching for help and found Dr Toru. It is 4 weeks since I started giving Moosya Dr Toru Protocol twice a day.
She put on weight, her hair has improved, and she is even playing with me.
I am going to order more of Dr Toru supplements.
Thank you very much.
Elena.
