Phase 1 Kidney Care Program
(corresponding to IRIS Stage 1 – early balance stage)
Most cats in this phase are still healthy.
Small internal changes may begin — often before any symptoms appear.
This is the best time to start gentle nutritional support for lasting balance.
At a Glance
- Kidney function: mostly normal, with only minor early changes
- Goal: maintain balance before progression
- Approach: early nutrition, hydration, and mindful observation
Step 1. Supplements
Early nutritional care can begin with two supplements that help maintain balance and reduce strain on the body.
✔ Dr. Toru Protocol – AIM-based supplement
- Helps maintain the body’s natural waste-clearing balance.
- Developed through the research of Dr. Toru Miyazaki on feline kidney health.
✔ Probiotics Protocol - Toxin Burden Support
- Supports healthy gut flora and internal toxin balance.
- Formulated with 9 probiotic strains and prebiotics for daily well-being.
Step 2. Diet & Hydration
Small changes can make a big difference.
✔ Diet
- Prescription renal diets are usually not required at this stage.
- Choose a balanced senior or maintenance formula.
- Feed smaller, more frequent meals to support stable metabolism.
✔ Hydration
- Place multiple water bowls around the home and refresh daily.
- Add water to dry food, or mix in wet meals and lickable treats to encourage intake.
Step 3. Routine Checkpoints
Focus on trends, not just numbers.
- Track appetite and energy — sudden changes may signal imbalance.
- Watch water intake — a sharp increase can mean extra stress on the kidneys.
- Weigh weekly — at the same time and conditions for consistency.
💡 Vet Visits (every 6–12 months)
- Ask for a general wellness exam including kidney markers, and an ultrasound if available.
Summary – Phase 1 Care
✔ Start early with Dr. Toru Protocol and Probiotics Protocol
✔ Keep diet and hydration balanced
✔ Stay aware and help maintain long-term stability
Reference
According to the IRIS Guidelines,
Stage 1 indicates that most kidney function remains.
Early nutritional care helps maintain balance before measurable loss occurs.
