Stage 2 Kidney Care Program
This stage should never be overlooked — it’s time to take it seriously.
Your cat may still look healthy, but early kidney decline may have already begun.
Now is the time to start structured care.

2. Diet & Hydration
From Stage 2 onward, it becomes important to manage diet and hydration more carefully.
✔ Diet Tips
- Begin transitioning to a renal-friendly or prescription diet.
- Choose formulas with controlled protein, phosphorus, and sodium levels.
- If your cat refuses a renal diet, mix it gradually with the current food to increase acceptance.
✔ Hydration Tips
- Add about 30 ml (≈ 1 fl oz) of water to wet food or liquid treats two to three times per day.
- Under veterinary guidance, early use of subcutaneous fluids can also be considered.
3. Routine Checkpoints
At this stage, regular checkups become increasingly important.
✔ Every 3–6 Months
- Schedule wellness exams with blood tests (Creatinine and BUN).
- Include an abdominal X-ray under veterinary guidance.
✔ Every Week
- Weigh your cat under the same conditions for accuracy.
- Track appetite and activity — sudden changes may indicate imbalance.
- Watch water intake — a sharp increase may indicate imbalance.
4. Emergency Signs
Seek veterinary attention if you notice:
- Complete loss of appetite or frequent vomiting
- Noticeable lethargy or labored breathing
- Rapid weight loss or sudden dehydration
Reference
According to the IRIS Guidelines, Stage 2 represents a moderate decline in kidney function.
At this stage, kidney function is about 33–66% of normal.
Creatinine levels typically range from 1.6 to 2.8 mg/dL, and BUN is usually between 16 and 35 mg/dL.
Values may vary depending on individual health status and laboratory standards.
