Cat Calories: Why Indoor Cats Gain Weight Easily

Indoor cats burn little energy roaming, yet food bowls are often kept full. A calorie estimate shows how small the daily budget really is.

What is the Cat Calorie Calculator?

Enter your cat's weight and lifestyle, and the tool estimates resting energy and daily calories. This is a guide, not veterinary advice, and it assumes a healthy adult cat at a stable weight.

How to use it

  1. Enter your cat's weight.
  2. Pick lifestyle.
  3. Click Calculate Cat Calories.

Worked example

For a 4 kg indoor neutered cat, resting energy is about 197.99 kcal and daily need is about the same.

Do kittens use the same formula?

No. Growing kittens need considerably more per kilogram, so this adult guide should not be used for them.

Frequently asked questions

Is this veterinary advice?

No. It is a standard-formula guide for healthy adults.

My cat begs for more. Should I give in?

Begging is often habit, not hunger. Stick to the measured amount and check weight monthly.
