Greycoat Research Expert Guidance for CKD Cats
With over 1,000 consultation cases worldwide, Greycoat Research provides expert-backed guidance for CKD cats, helping them maintain kidney health and manage the progression of CKD through data-driven care.

Dr. Toru Miyazaki was the first to uncover the mechanism behind cat CKD.
Dr. Toru Miyazaki, the world's leading authority on AIM research, provides Greycoat Research with expert guidance in developing AIM-based supplementation to support kidney function. His research has contributed to innovative treatments that help manage CKD in cats.
Byeol, a 2-year-old cat, had no history of kidney disease but was monitored due to concerns about kidney health. She was introduced to AIM-based supplementation to support her renal function. Over the course of a month, her creatinine levels showed slight improvement, and her kidney values remained stable.

Byeol’s Health Improvements
Byeol began AIM supplementation in August 2024. By September, her kidney values remained stable, with slight improvements in creatinine levels.
Health Metric | Before | After | Change |
---|---|---|---|
Creatinine (CRE) | 1.9 | 1.8 | Slight Decrease (Stable kidney function) |
BUN Levels | 22 | 24 | Slight Increase (Monitor hydration) |
Phosphorus (PHOS) | 4.4 | 3.9 | Decreased (Balanced phosphorus levels) |
Weight | 5.0 kg | 5.19 kg | Slight Increase (Weight management advised) |

How Did Byeol Improve?
Energy & Activity
- Increased energy levels, with more willingness to play.
- Showed more interest in toys than before.
Weight & Appetite
- Weight increased slightly; owner was advised to maintain current weight.
- Noticeable increase in appetite.
Appearance & Other Changes
- Started vocalizing more and engaging in social interactions.
Supplement Adjustments
- Started with Dr. Toru Protocol, Intensive Protocol, probiotics, and omega-3 supplements.
- Continued monitoring with no adjustments needed at this stage.
Byeol’s kidney values remained within a healthy range, with a slight decrease in creatinine and phosphorus levels observed within just 1 month of supplementation. Additionally, her appetite and energy levels improved, and she showed more interest in play. While her weight slightly increased, maintaining a healthy balance is essential, as excessive weight gain can also be a concern in feline health management. Given that weight loss is a common concern among CKD cats, the fact that Byeol has been able to avoid losing weight is still a promising sign.
Testimonial from Byeol’s Owner

"I started Byeol on Dr. Toru Protocol and Intensive Protocol to support her kidney health, and I’m thrilled to see her creatinine levels go down. She’s eating better, has more energy, and seems happier overall. It's great to see her enjoying her youth like a kitten should!"
