Introduction
Chronic Kidney Disease (CKD) is one of the most common health problems in older cats. If your cat has been diagnosed with kidney issues, switching to a renal-supportive diet can make a big difference in their comfort, energy, and longevity.
But is homemade cat food safe for kidney disease?
✅ Yes — with proper guidance and vet-approved recipes, homemade food can support kidney health while being fresh, safe, and tailored to your cat’s needs.
This guide will help you:
- Understand what cats with kidney disease need
- Know what to avoid
- Try easy homemade renal-friendly recipes

⚠️ Why Diet is Critical for Cats with Kidney Disease
Kidneys help remove waste and maintain fluid balance. When they stop functioning properly, toxins build up in the body, leading to vomiting, weakness, and loss of appetite.
Goals of a kidney-supportive diet:
- Lower phosphorus intake
- Moderate protein quality (not quantity)
- Higher moisture content
- Controlled sodium and potassium levels
- Added omega-3 fatty acids for inflammation
⚠️ Important: Always consult your vet before switching to homemade food for a cat with CKD.
