Dolphin, a 9-year-old cat, was diagnosed with polycystic kidney disease (PKD). Her owner also noticed that Dolphin was often withdrawn and spent excessive time sleeping. After introducing AIM-based supplementation, Dolphin demonstrated notable improvements in both her physical condition and behavior over three months.

How Did Dolphin Improve?
Energy & Activity
- Previously lethargic, Dolphin became significantly more active.
- Increased exploration of her environment and interaction with her owner.
- Reduced excessive sleeping, indicating improved overall vitality.
Weight & Appetite
- Maintained a stable weight with a more consistent appetite.
- Adapted well to supplementation after an initial adjustment period.
Appearance & Other Changes
- Increased self-expression—Dolphin began seeking attention and vocalizing her needs.
- Overall health condition noted as "improved" by her veterinarian.
Supplement Adjustments
- Initially started with a small dosage of Dr. Toru Protocol to accommodate her sensitive digestion.
- Gradually increased to 1/2 capsule daily after monitoring tolerance.
- Owner reported increased confidence in managing Dolphin’s PKD with AIM care.
A cyst on Dolphin's left kidney decreased in size from 2.5 cm to 1.5 cm, and her energy levels dramatically improved over 3 months. She became more interactive, less withdrawn, and maintained stable kidney values despite her PKD diagnosis. These positive changes highlight the potential benefits of AIM-based supplementation in managing feline kidney health.
Testimonial from Dolphin’s Owner

"I was really worried about Dolphin’s condition, especially since she spent so much time sleeping and seemed so withdrawn. After starting AIM supplements, I started noticing small changes—she was more awake, more interested in her surroundings, and even started waking me up to demand food and treats! The biggest surprise was her kidney cyst shrinking from 2.5 cm to 1.5 cm in just 3 months. Her vet was amazed! I’m so thankful for Greycoat Research’s guidance and support. Seeing Dolphin so much more energetic gives me hope for the future."
