How Much to Feed a Cat

An average 10-lb indoor adult cat needs approximately 200-250 calories per day. This translates to roughly 1/3-1/2 cup of dry kibble or 1.5-2 cans (5.5 oz) of wet food. The exact amount depends on activity level, age, and whether the cat needs to lose or gain weight.

Wet vs Dry Food

Wet food advantages: Higher moisture content (cats are chronically dehydrated), lower carbohydrates, cats generally prefer it, better for urinary health. Dry food advantages: Convenience, longer shelf life, dental benefits (slight), lower cost. The ideal diet for most cats is a mix — wet food for hydration and protein, dry food for convenience and dental health.

⚡ CalcWolf Insight

Cats are obligate carnivores — they require animal protein and cannot thrive on plant-based diets. Look for foods where the first 2-3 ingredients are named animal proteins (chicken, turkey, salmon), not grains or by-products. Protein should be 30%+ of the food by weight.

Frequently asked questions
Should I free-feed my cat?
Not recommended for most cats. Free-feeding (leaving dry food out all day) leads to overeating — 60% of US cats are overweight. Measured meals twice daily give you better portion control and help you notice appetite changes that may signal health issues.
How do I know if my cat is overweight?
Feel the ribs — you should be able to feel them easily with light pressure. From above, your cat should have a visible waist. From the side, the belly should tuck up slightly. If you cannot feel ribs without pressing firmly, your cat is overweight.
