Understanding Senior Cat Nutrition & Kidney Health

As cats age, their kidneys work harder to filter waste. Reduced kidney function leads to:

  • Dehydration (they can’t concentrate urine well).
  • Weight loss (due to protein loss).
  • Lethargy (toxins build up in the blood).

Senior Cat Nutrition Tips

To ease kidney strain, look for:

  • Wet food (70–80% moisture) to prevent dehydration.
  • Low phosphorus (<0.5% dry matter) to slow CKD.
  • Moderate high-quality protein (25–35%) to maintain muscle.
