Cat Food Calculator
How much should you feed your cat? Weight alone is a weak signal — body condition score matters more — but a starting portion from resting-energy math beats guessing from the scoop on the bag. This worked example uses a 10 lb neutered adult at roughly 400 kcal per cup (always check your bag; dry food commonly runs 300–500 kcal per cup).
Use the controls below to enter your cat's weight, life stage, and the calorie density printed on your food. Portions round down to the nearest 1/8 cup so you do not overfeed. Download a two-page PDF: feeding chart on page 1 and a 30-day log on page 2 for your fridge or pet sitter.
An estimate from standard formulas — your veterinarian's recommendation wins, especially for kittens, seniors, pregnancy, or any medical condition.
