How This Calculator Works
Cat calorie needs are calculated using the standard RER formula:
RER = 70 × (body weight in kg)0.75
A multiplier is then applied based on life stage, activity, and neutering status to determine daily calorie needs.
Cat-Specific Multipliers
| Cat Type | Multiplier |
|---|---|
| Neutered indoor adult | 1.2 |
| Intact indoor adult | 1.4 |
| Active outdoor cat | 1.4 - 1.6 |
| Kitten | 2.5 |
| Senior cat | 1.0 - 1.1 |
| Overweight (weight loss) | 0.8 |
Feeding Tips for Cats
- Most cats prefer smaller, more frequent meals — 2-4 times daily is ideal
- Wet food helps with hydration, especially for cats that don't drink enough water
- Free-feeding dry food can lead to overeating — measured portions are better
- Cats are obligate carnivores — look for foods with high protein content (30%+ dry matter)
