Buying Guide
For diabetic cats, aim for under 10% carbohydrates on a dry matter basis — ideally under 5%. High protein content (40%+ DM) helps stabilize blood sugar. Wet and canned foods are preferred over dry kibble for carbohydrate control. Always work with your veterinarian to coordinate diet changes with insulin dosing.
Key Nutritional Criteria to Evaluate
When choosing the best food for your cat’s specific needs, always look for:
- AAFCO Statement: Ensure the food is “complete and balanced” for your cat’s life stage
- Named protein source: Real chicken, salmon, etc. — not generic “meat” or “poultry”
- Moisture content: Higher moisture (wet food) benefits hydration
- Ingredient quality: Avoid artificial colors, flavors, and preservatives
Frequently Asked Questions
Can diet alone manage feline diabetes?
Diet alone may not manage all diabetic cats, but a proper low-carb, high-protein diet significantly improves glucose control and can reduce insulin requirements. Some cats achieve remission through diet.
What foods should diabetic cats avoid?
Avoid high-carbohydrate foods including dry kibble, treats with corn or wheat, and sweet potato-heavy formulas. Limit carbohydrates to under 10% DM.
Should diabetic cats eat wet or dry food?
Wet food is strongly preferred for diabetic cats because it is significantly lower in carbohydrates than dry kibble, making blood glucose control much easier.
How often should I feed a diabetic cat?
Typically, diabetic cats should be fed right before insulin injections to synchronize food intake with insulin action. Your vet will advise on the specific feeding schedule based on your cat’s insulin regimen.
