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.
Greycoat Research is guided by a team of experts dedicated to advancing feline kidney care. Dr. Toru Miyazaki, a leading authority on AIM research, has been instrumental in developing innovative approaches to CKD management. Dr. Kim Jae-young, a Korean veterinarian, gained recognition for his exceptional care of Minky, the longest-living cat in Korea at 28 years old. Dr. Kobayashi Motoo, a Japanese veterinarian with over 30 years of clinical experience, was the first to apply AIM in feline kidney treatment. Their combined expertise helps shape effective CKD care solutions for cats worldwide.
Isaac, a 3-year-old male cat, was diagnosed with CKD at just 8 months old due to being born with abnormally small kidneys. His kidney values remained in the early-stage CKD range, and he struggled with high phosphorus levels despite careful dietary management. With AIM supplementation, Isaac demonstrated improved energy levels and overall well-being while maintaining stable kidney function.

Over 6 months, Isaac’s energy levels improved, his phosphorus levels became more manageable, and he maintained stable kidney function despite his early CKD diagnosis.

His adaptation to AIM-based supplementation contributed to his overall well-being, allowing him to continue living an active and stable life despite being born with abnormally small kidneys.
Testimonial from Isaac’s Owner

"Isaac was diagnosed with CKD when he was just a kitten, and I was constantly worried about his long-term health. Since he was born with small kidneys, I knew I had to be proactive about his care. Even though I did my best not to give him too many snacks, his phosphorus levels were difficult to control. After starting AIM supplements, I noticed he was more energetic and playful than before. When I recently took him to the vet, I was told that his kidneys weren't shrinking as quickly as before, too! Thank you, Greycoat Research!"
