Buying Guide
Wet and canned foods are generally much lower in carbohydrates than dry kibble. Most pate-style wet foods contain under 5% carbs DM. Grain-free dry foods typically range from 15-25% carbs DM. For diabetic cats, aim for under 10% carbs DM.
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
What percentage of carbs is considered low-carb for cats?
Generally, under 10% carbohydrates on a dry matter basis is considered low-carb. For diabetic cats, some vets recommend under 5%.
Do cats need any carbohydrates?
Cats have no dietary requirement for carbohydrates. Their bodies can derive glucose from amino acids via gluconeogenesis. Low-carb diets mimic their natural prey-based diet.
Can a low-carb diet reverse diabetes in cats?
In some cats with Type 2 diabetes, a strict low-carb, high-protein diet combined with insulin therapy can lead to diabetic remission. Work closely with your veterinarian.
Is grain-free the same as low-carb?
Not necessarily. Grain-free foods replace grains with legumes or potatoes, which can still be high in carbs. Always check the actual carbohydrate content.
