Cat Food Portion Calculator
Enter your cat's weight, life stage and the food's energy. The calculator applies the same veterinary formula vets use - 70 × kg^0.75 with a stage factor - and returns grams per day and per small meal.
Cat portions live or die by precision: ten grams of overpour is a tenth of the day. This calculator shows that arithmetic, explains the indoor-cat multiplier owners underestimate, and rules by silhouette rather than by bag.
How to use
- Use the last vet-visit weight; enter kcal/kg from the food panel.
- Pick the honest stage - neutered indoor is the most common and the lowest multiplier.
- Weigh the daily total once, split into 3-4 small meals, adjust 10% monthly by the ribs-and-waist test.
Frequently asked questions
How much should a 4.5 kg cat eat per day?
A neutered indoor 4.5 kg cat needs about 250 kcal - roughly 65 g of 3,800 kcal/kg food. The bag table usually says more; the indoor multiplier and the scale decide the truth.
Why do indoor cats gain weight so easily?
The lowest energy multiplier meets the highest feeding optimism: neutered indoor cats burn less and eat by boredom. Measured portions, wet food for volume, and food-puzzle toys close the gap without a diet drama.
How many meals should a cat eat per day?
Three or four small meals matches the natural hunt-eat-sleep cycle; two big meals work if that is reality. The 5 a.m. serenade is usually a scheduling bug - shift the last meal later before blaming the cat.
How do I check if my cat is overweight?
Ribs findable under slight fat, waist visible from above, no swinging belly flap when walking. Cats should weigh what their frame says, not a breed chart - adjust the ration 10% monthly and let the silhouette vote.
