Greycoat Research was founded with a singular, heartfelt mission: to extend longevity and enhance the quality of life for cats navigating kidney health challenges.

What began as a personal search for better answers has grown into a global, research-led organization dedicated to feline renal care.

At the core of our work is a science-driven approach grounded in AIM-based mechanisms, the integration of emerging research findings, and continuous formulation development supported by ingredient-level studies and published scientific perspectives.

Today, operating from both South Korea and the United States, we support pet parents in over 20 countries with evidence-based nutritional guidance and specialized care.

Our commitment is also deeply clinical.

Through more than 3,500 individual consultation cases, and with protocols implemented in the care of over 20,000 cats in Korea, Greycoat Research has built one of the most practice-backed renal care frameworks available for cats.

At Greycoat Research, we believe that a diagnosis is not the end of the story. It's the beginning of a more informed, structured, and empowered journey for you and your feline companion.
