Their combined expertise helps shape effective CKD care solutions for cats worldwide.
Geumdong, a 16-year-old cat, had always been an active and playful companion. However, his energy levels dropped significantly 2 years ago, and his owner assumed it was simply due to aging. He was also recently diagnosed with arthritis, which further limited his mobility. Concerned about his declining activity, his owner introduced AIM supplementation, hoping to support his joint health and overall vitality.
Meet Geumdong

Health Metric | Before | After | Change |
---|---|---|---|
Energy Levels | Low | More active and engaged | Increased movement |
Mobility | Limited | Jumping and running | Improved agility |
How Did Geumdong Improve?
Energy & Activity
- Within just a few days of AIM supplementation, Geumdong’s energy levels increased.
- He began running around the house, showing excitement and engagement.
Weight & Appetite
- Appetite remained stable, and there were no issues with meal consumption.
- Experienced no vomiting issues while taking AIM supplementation.
Appearance & Other Changes
- No significant external changes were reported.
Supplement Adjustments
- Dr. Toru Protocol was introduced and administered for 2 months before circumstances prevented the owner from re-administering it.
- Dr. Toru Protocol was reintroduced after a break of several months, leading to rapid improvements.
Within days of AIM supplementation, Geumdong was climbing, running, and playing again—activities he had long abandoned. When circumstances prevented his owner from continuing supplementation, Geumdong’s energy levels dipped noticeably. However, once AIM care was resumed, he once again regained his vitality, demonstrating just how much of a difference it made in his daily life.
Testimonial from Geumdong’s Owner

“I thought Geumdong was just slowing down with age, but after just a few days on Dr. Toru Protocol, he was full of energy again! I can't even remember the last time he climbed on top of his cat tower or the cabinet, but he started doing it almost right away! He even began chasing his favorite toys like he did when he was younger. I had to stop giving him Dr. Toru Protocol for a while, and it broke my heart to see him go back to being tired and sleepy again! Thankfully, I was recently able to give him some more, and it's such a relief to see him so active and happy again!!”
