Cat Food Portions: Small Cat, Small Margin for Error
Cats are small, so a few extra grams a day add up fast. A weight-based estimate beats guessing from the packet alone.
What is the Cat Food Portions Calculator?
Enter your cat's weight, lifestyle, and the food's energy per 100 grams, and the tool estimates daily calories and grams. This is a guide based on standard resting-energy formulas, not veterinary advice, so adjust for body condition and check with your vet for kittens, illness, or weight problems.

Worked example
For a 4 kg indoor neutered cat on 350 kcal per 100 g food, resting energy is about 197.99 kcal, daily need the same, and daily food about 56.57 g.
Do indoor cats need less food?
Usually yes. Less roaming means less energy burned, which is why indoor neutered cats get the lowest factor here.
