Soommu could barely eat, barely move. 128 days later, he climbed back onto my lap.
Soommu (9) · Korea · Weight 4.1 kg → 4.8 kg
Editor's Note
Stage 4 diagnosis, ongoing daily challenges, and a care routine that required steady, active attention. We chose Soommu's story because his guardian helped support a more stable daily life through consistent observation and hands-on care. We're sharing this not as a miraculous recovery case, but as an exemplary care model that other cat guardians can learn from and adapt to their own cats.
'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.
