Why Senior Cats With Kidney Disease Need Special Wet Food

Chronic Kidney Disease (CKD) is one of the most common health conditions in cats over 10 years old. As kidney function declines, waste products build up in the bloodstream. Nutrition becomes the most powerful tool to slow progression.

The Right Renal Diet Helps:

Reduce phosphorus intake
Support hydration
Maintain muscle mass
Control blood pressure
Improve appetite

Wet food is strongly recommended because hydration is critical for cats with reduced kidney function.

What to Look for in the Best Wet Cat Food for Kidney Disease

1. Low Phosphorus Content

High phosphorus accelerates kidney damage. Look for:

Phosphorus under 0.6% (dry matter basis) for moderate to advanced CKD
Clearly labeled phosphorus values

2. Moderate, High-Quality Protein

Cats still need protein, but in controlled amounts.

Look for:

Real meat as first ingredient
Highly digestible protein
No excessive fillers

3. High Moisture Content

Wet food supports hydration and helps flush toxins.

Ideal moisture: 75–82%

4. Added Omega-3 Fatty Acids

Omega-3s from fish oil may help reduce kidney inflammation.

Look for:

DHA
EPA
Fish oil sources
