Cat Calorie Calculator (Daily kcal Needs)
This Cat Calorie Calculator estimates how many calories your cat needs per day based on weight, life stage and activity. It’s a simple way to sanity-check feeding amounts and spot potential underfeeding or overfeeding risks.
Estimate your cat’s daily calorie needs
Enter your cat’s weight and basic lifestyle details to see:
- Estimated daily calorie needs (kcal per day)
- Recommended range for typical maintenance
- How current feeding might compare to the estimate

Example
4 kg neutered indoor adult cat
- Typical daily needs: ~200–230 kcal/day.
- Feeding significantly above this may lead to weight gain.
- Feeding well below this could risk underfeeding over time.
How to use your cat’s calorie estimate
1. Compare to the food label
Check how many kcal per cup, can or pouch your cat’s food contains, then see how your current portions compare to the estimated daily need.
2. Adjust gradually
If your cat needs a change in calories, adjust portions slowly over 1–2 weeks to avoid digestive upset and to monitor appetite and behavior.
3. Watch body condition, not numbers only
Use weight, waist shape and your vet’s body condition score along with calorie estimates. Numbers are a guide, but how your cat looks and feels is key.
