Is grain-free cat food automatically better?
No - grain-free doesn't mean low-carb, and it doesn't guarantee a better score. What matters is what replaces the grains, and the answer is often just as carbohydrate-dense.
"Grain-free" is a marketing term, not a nutritional standard. Many grain-free foods replace wheat and corn with peas, lentils, potatoes, and tapioca, which are equally high in carbohydrates.
The grain-free myth
The logic behind grain-free sounds reasonable - cats don't eat grains in the wild, so removing them should make a food more species-appropriate. In practice, removing grains is only beneficial if what replaces them is not another carbohydrate source.
What actually makes a food better
Whether carbs come from rice, corn, peas, or potatoes - they're all carbohydrates. A grain-free food with 40% dry matter carbohydrates from legumes is no better for a cat than a grain-inclusive food at the same level. The total carb percentage is what matters, not where it comes from.
A food is more species-appropriate when it has more protein from named animal sources - not simply because it removed grains. Look at the dry matter protein percentage and what it comes from.
Grain-free or not, the ingredient quality signals are the same: named whole meats or meat meals in the first positions, no vague "meat" or "poultry" without a species name, minimal by-products.
Instead of filtering by "grain-free", use Cat Food Central to compare actual dry matter carbohydrate percentages and protein sources. That tells you far more than whether grains are present.
