Quick answer

Our top pick is Hill’s Science Diet Adult Indoor Cat Food. It balances lower calories with high-quality protein to help heavier indoor cats maintain a healthy weight. For cats with sensitive stomachs, Purina Pro Plan Sensitive Skin & Stomach is a great alternative. If you prefer wet food, Wellness CORE Grain-Free Pate provides moisture and protein without excess carbs.

What to consider for Indoor Cat Food For Cats Over 15 Lbs

Cats over 15 lbs are often overweight or large-breed. Indoor cats have lower energy needs, so calorie density matters. Look for foods with moderate fat (around 12-15% dry matter) and higher protein (35-45%) to preserve muscle mass. Fiber helps with satiety and hairball control. Wet food can aid hydration, which is important for urinary health. Always consult your vet before making dietary changes.

What to look for in a cat food

First, ensure the food has an AAFCO statement confirming it is complete and balanced for adult maintenance. The first ingredient should be a named meat (like chicken or salmon). Animal protein and taurine are essential for heart and eye health. For indoor cats, moderate fat and added fiber (like beet pulp) support weight management. Wet food provides moisture for urinary tract health. Choose a formula appropriate for your cat’s life stage (adult or senior).

How we chose these picks

  • Evaluated calorie content and macronutrient profiles for weight management.
  • Checked that protein sources are named and animal-based.
  • Verified AAFCO nutritional adequacy statements.
  • Considered brand reputation and quality control history.
  • Read ingredient lists for unnecessary fillers or artificial additives.
  • Included a mix of dry and wet options to suit different preferences.
  • Reviewed customer feedback for palatability and digestive tolerance.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Foods with unnamed meat or by-products as the first ingredient.
  • Recipes with insufficient taurine (most commercial foods are fine, but avoid generic brands).
  • All-life-stages formulas for adult cats without checking calorie density.
  • Abrupt diet switches; transition over 7-10 days to avoid digestive upset.
