Cat Food Calculator
Estimate daily calories for a healthy cat, split wet and dry food using the labels, and print a feeding card. Free, private and no signup.
Turn a calorie estimate into cups, cans and a feeding card. Use the calorie values on your food labels. Everything you enter stays in this browser; nothing is saved.

How the estimate works
We use the AAHA resting-energy equation: 70 × body weight in kilograms to the power of 0.75, multiplied by a feline life-stage factor. These are starting estimates, not a nutritional assessment.
Both kitten age bands use the feline growth factor of 2.5. For adults, the normal/active choices use the lower/upper ends of AAHA’s ranges: 1.2–1.4 for neutered cats and 1.4–1.6 for intact cats. Low activity uses 1.0. This choice within a range is a calculator convention, not a measured activity formula. Senior cats do not get an automatic calorie cut.

Use the food you actually feed
The daily total includes treats. We allow up to 10% for treats and divide the remainder by your food’s kcal per cup or whole can. A mixed diet is split by calories, not volume. Use matching recipe and can-size labels; there is no universal calorie density.
Body scores of 4–5 on a nine-point scale are the ideal range. Outside that range, or for weight change, the tool requires a vet-entered calorie target. Cats can need substantially more or less than an estimate. If your cat stops eating, contact your veterinarian promptly.

When this calculator is not enough
It does not plan diets for medical conditions, pregnancy, nursing or unweaned kittens. It cannot guarantee a safe pace of weight loss. Significant restriction can require a specially formulated diet and a monitoring plan from your vet.

Frequently asked questions
Does this tell me exactly how much my cat needs?
No. It estimates a starting amount for a healthy cat, then converts calories using your food labels. Your veterinarian can help adjust it to weight, body condition and health.
Can I use it for weight loss or weight gain?
Only to split a daily calorie target already agreed with your vet into food portions. The calculator does not choose a calorie deficit or predict a safe rate of weight change.
Do treats get added to the daily calories?
No. The selected treat allowance is taken out of the total, leaving the remaining calories for complete food. You can leave the allowance at zero.
Are my cat’s details saved or shared?
Inputs and calculations stay in your browser and are not saved. The optional share button sends only the feeding card you choose to share. Usage analytics do not include your inputs or results.
