Cat Food Calculator
Estimate how much wet or dry cat food to feed per day using your cat's weight, life stage, goal, and food label. The calculator automatically recommends meals per day from your cat's age stage, so you only need to enter the details that affect the food amount.

Cat Food Chart by Age and Weight
This chart shows rough daily amounts using the calculator's default food settings: 400 kcal per cup of dry food and 180 kcal per 5.5 oz can of wet food. Meal counts are automatic and age-based: younger kittens get more meals, while adult and senior cats use a common 2-meal routine.

How the Cat Food Calculator Works
The calculator estimates daily calories from weight, then converts that calorie target into wet food, dry food, or a custom label amount. The fastest path is to enter weight, choose age stage, and keep the default food setting if the label is not nearby.
It uses a resting energy estimate from body weight and applies a practical life-stage or goal multiplier. That makes the result a starting point, not a prescription.
Enter weight
Weight is the main input. Use your cat's current weight unless your veterinarian gives you a target weight.
Choose age stage and goal
The age stage controls the meal schedule, while the goal and spay/neuter status help adjust the calorie estimate.
Use the label if you have it
Update kcal per cup or kcal per can when you know it. If not, the default gives a quick starting point.
What Changes Your Cat's Food Amount
Food calories
A dense dry food can need a much smaller cup amount than a lighter recipe.
Wet vs dry food
Wet food usually looks like more volume because it contains more water.
Spay/neuter status
For adult cats, whether a cat is spayed or neutered matters more than male or female sex alone.
Treats
Treats count toward the day's intake, especially for indoor cats.
Body condition
If your cat is gaining or losing weight, adjust gradually and recheck the label.
FAQ
How much food should I feed my cat?
Start with your cat's current weight, age stage, goal, and the food label. The calculator gives a daily estimate, then automatically splits it into age-based meals.
Can I use this cat food calculator for wet food?
Yes. Choose wet food and the calculator estimates cans per day, cans per meal, grams per day, and daily calories.
What if I do not know the calories on the cat food label?
Use the default dry or wet food setting first. If you later find the kcal per cup or kcal per can on the label, update the field for a closer estimate.
Should kittens eat more than adult cats?
Yes. Kittens usually need more energy for growth and more frequent meals. This calculator uses 4 meals for 6-12 week kittens, 3 meals for 3-6 month kittens, and 2 meals for 6-12 month kittens.
Do treats change how much cat food to feed?
Yes. Daily treats add calories. If treats are part of the routine, keep meal portions slightly smaller and watch body condition.
Do male and female cats need different food amounts?
Sex alone is usually not the main input for a feeding estimate. Weight, age, body condition, activity, and whether the cat is spayed or neutered matter more.
When should I ask a vet about cat feeding?
Ask a veterinarian if your cat needs weight loss, is losing weight, gaining quickly, refusing food, vomiting, diabetic, pregnant, nursing, or on a prescription diet.
