Quick answer
Our top pick is Hill’s Science Diet Adult Indoor Cat Food, Chicken Recipe, because it provides high-quality chicken protein with controlled calories to help manage weight in larger cats. For owners seeking a grain-free option with even higher protein, Instinct Original Grain-Free Pate offers 95% animal ingredients. Royal Canin Feline Health Nutrition Indoor Adult Dry Cat Food is excellent for cats prone to hairballs.
What to consider for High Protein Cat Food For Cats Over 15 Lbs
Cats over 15 pounds often have lower energy needs per pound than smaller cats, so they require a nutrient-dense food that is high in protein but not excessively high in calories. Protein supports lean muscle mass, which is crucial for joint health and mobility. Look for a named animal protein as the first ingredient, and ensure the food meets AAFCO nutrient profiles for adult maintenance. Some larger cats may have a tendency toward obesity, so a formula with moderate fat and fiber can help them feel full while maintaining a healthy weight. Additionally, consider wet food options to increase moisture intake, which supports urinary tract health.
What to look for in a cat food
First, verify the food has an AAFCO statement confirming it is complete and balanced for the appropriate life stage (adult or all life stages). The first ingredient should be a named meat source like chicken, turkey, or fish. Cats are obligate carnivores, so animal protein should be abundant and taurine must be added (or naturally present) to prevent heart and eye issues. For cats over 15 pounds, a moderate fat content (around 15-20% on a dry matter basis) helps prevent weight gain. Moisture content matters: wet food provides hydration that supports kidney and urinary health. Finally, choose a formula suited to your cat’s age and any specific health needs, such as indoor or hairball control.
