Cat Daily Food Calculator
Daily Food Amount
Formula
RER = 70 x (weight_kg)^0.75. Daily Calories = RER x life stage factor (kitten 2.5, adult 1.2, senior 1.0) x activity factor (low 0.85, moderate 1.0, high 1.2) x condition factor (underweight 1.2, ideal 1.0, overweight 0.8). Wet food ~28 kcal/oz, Dry food ~375 kcal/cup.
Frequently Asked Questions
How much wet food should I feed my cat?
An average 10-lb adult cat needs about 200-250 calories per day, which translates to roughly 7-9 oz of wet food daily (about 1.5 standard 5.5-oz cans). This varies by your cat's age, activity level, and the specific food's calorie content.
Is wet or dry food better for cats?
Both have benefits. Wet food provides better hydration (important since cats have a low thirst drive), higher protein, and fewer carbs. Dry food is more convenient and can help with dental health. Many vets recommend a combination of both for optimal nutrition and hydration.
Should I free-feed my cat dry food?
Free-feeding (leaving food out all day) can lead to overeating and obesity, especially in indoor cats. Measured meal feeding 2-3 times per day is generally recommended to maintain healthy weight. If you free-feed, carefully measure the daily amount and don't refill until the next day.
