Is your cat just sleeping?
Recharge your cat’s vitality battery. 🔋
Is your cat just resting, or is it a decline in their natural vitality?
Recharge their cellular energy with Intensive Protocol from Greycoat Research.
The Core Problem: It’s Not Just Age, It’s a "Battery" Issue
As our companions age, we often mistake their decreased activity for a "peaceful life" or assume they’ve simply "settled down.
However, it is a critical 'Low Battery' signal from their cellular health.
When energy is depleted, rest is actually a natural energy conservation—minimizing movement to save what little is left.
At the cellular level, the body may need extra support to regain its spark.
The Solution: Beyond Basic Nutrition
Restoring vitality requires more than simple nutrition.
We must directly support the master switch of energy within the cell.
Greycoat Research has set a new standard for support, built on three core scientific mechanisms.
✅Energy Balance
✅Antioxidant Support
✅Cellular Metabolism
Recharge your cat’s vitality battery today.

Intensive Kidney Support
Designed to complement Dr. Toru
when more intensive support is needed.
Why Is Intensive Needed?
Intensive builds on
the AIM-based kidney care of Dr. Toru,
adding focused support for:
- Energy balance
- Antioxidants

When Intensive Is Especially Helpful
- 7+ years old
and kidney care is already part of the routine - Dr. Toru is used daily,
but consistency feels harder to maintain - Kidney condition or
daily energy doesn’t feel the same as before
Many guardians choose to add Intensive
not after a setback,
but when small fluctuations first appear.
