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.
