[Stage 2 CKD] Rei - BUN 54.8 → 30.7 in 1 Year

1-Year Experience with AIM-Based Dr. Toru Protocol: Changes in 6-Year-Old Cat Rei Diagnosed with Stage 2 CKD

Rei, a 6-year-old cat, was diagnosed with Stage 2 chronic kidney disease (CKD) in early 2024. In June 2024, her guardian began using the Dr. Toru Protocol to support kidney function. Although Rei’s appetite gradually improved, her stools remained slightly hard, prompting the addition of the Probiotics Protocol when it launched in December 2024.

After nearly a year of consistent care with targeted supplementation, Rei’s bloodwork showed meaningful changes—her BUN dropped sharply, and creatinine moved from the Stage 3 borderline to a more stable Stage 2 range. Her hemoglobin and hematocrit values also returned to more favorable levels, suggesting better anemia support.

Guardian’s Message 💬

"Rei was diagnosed with Stage 2 CKD last year, and we began Dr. Toru Protocol in June 2024. Although she seemed better overall, her stool was still a bit firm. After the Probiotics Protocol launched in December, we added it in—and it made a noticeable difference.

Her latest bloodwork showed that her BUN dropped dramatically, and her creatinine moved from Stage 3 borderline to a stable Stage 2 range. Her energy is back, she’s eating well, and her personality is livelier than ever. I’m so relieved to see her thriving again.

Consistent care really seems to be the key."
