Cat food amount calculator for cans, cups and grams

A cat food amount calculator should answer a simple question: how much of this specific food should I feed? BowlMath uses the calories on the label so the answer matches cans, pouches, cups or grams.

What this page is for

Two foods can have very different calories in the same-looking serving, so BowlMath asks for kcal per unit instead of guessing from volume.

What to have ready

For wet food, enter kcal per can, pouch, tray, ounce, gram or 100g.

How BowlMath calculates it

For dry food, grams are usually cleaner than cups, but cups can be used if the label gives kcal per cup.

How to use the result

Daily treats should come out of the same calorie budget before meal portions are calculated.

BowlMath gives a practical starting estimate, not veterinary advice. If your cat is underweight, overweight, diabetic, on a therapeutic diet, pregnant, nursing, eating poorly or changing weight unexpectedly, ask your veterinarian before changing portions.

Does this replace a vet feeding plan?

No. Use your veterinarian's targets for medical conditions, therapeutic diets or planned weight loss.

Can I use wet and dry food together?

Yes. Use a calorie split, fixed wet amount or fixed dry amount so all foods share one daily budget.
