Helping Milo feel like himself again started with small daily habits.
Milo (14) · Korea 🇰🇷 · Creatinine 2.20 → 1.81
Editor's Note
What stood out most in Milo’s story was not only the change in his creatinine level, but also his guardian’s daily consistency. From giving supplements more comfortably to switching to wet food and paying closer attention to hydration, each small change became part of a routine that supported Milo over time.
'Greycoat Dr. Toru' started with Dr. Toru Miyazaki's AIM research.
Based on research into cats' AIM-related kidney sensitivities, Greycoat turns this science into a daily care routine.
