Estimates for general information

Cat Calorie Calculator gives estimates of daily calories and food amounts for cats. The numbers come from common veterinary energy formulas and the details you enter. They are for general information only.

Not professional advice

Nothing on this site is veterinary, medical, or nutritional advice for a particular cat. Nothing here is legal, tax, or financial advice either. The tool does not diagnose a condition, prescribe a diet, or replace a visit to a licensed veterinarian.

Every cat is different

Real cats can need 10% or more above or below an estimate. Breed, body build, muscle, health, medicine, stress, temperature, and food quality all matter. Use the result as a starting point. Weigh your cat regularly and adjust with your vet.

Talk to a vet first if

  • Your cat is a kitten, or is pregnant or nursing.
  • Your cat is sick, recovering, or taking medicine.
  • Your cat has a long-term condition, such as diabetes, thyroid disease, or urinary or digestive problems.
  • Your cat is too thin, or has lost or gained weight quickly.
  • Your cat needs a special or prescription diet.

Cats that lose weight too fast, or stop eating, can develop serious liver problems. If your cat stops eating for a day or more, contact a vet.

Check the figures yourself

You are responsible for checking the numbers you enter and the results you use. Food calorie values come from you, and we do not verify them. Compare the result with your food label and your vet’s guidance before you change how you feed your cat.

Limitation of responsibility

We work to keep the formulas correct, but we do not promise that the tool is free of errors or right for your situation. To the fullest extent allowed by law, we are not responsible for any loss, harm, or cost that results from using, or being unable to use, this site or its results. See the Terms of Use for more.
