Understanding Your Cat's Calorie Needs
Obesity in cats is increasing. Excessive calorie intake increases the risk of diabetes, joint disease, and heart disease. Proper calorie management is the first step to ensuring your cat's healthy lifespan.
Calorie Differences by Weight
Larger cats need more calories, but not proportionally. A 2kg cat needs about 50% the calories of a 4kg cat. This is because larger bodies have more efficient metabolism. Larger cats may need less food than expected.
Calorie Changes by Life Stage
- Kittens: Highest calorie needs (RER × 2.5). Growth and development require lots of energy.
- Adult cats: Moderate calories (RER × 1.2). Weight maintenance is important.
- Senior cats: Lower calories (RER × 1.0). Reduced activity decreases calorie needs.
Impact of Activity Level on Calories
Outdoor, active cats need 20% more calories than indoor cats. Conversely, indoor cats with low activity should have 20% reduced calories. Seasonal changes can also slightly affect calorie needs.
Typical Calorie Guide by Cat
- Kitten (1-3kg): 150-250 kcal/day
- Small adult (3-4kg): 180-220 kcal/day
- Medium adult (4-5kg): 210-250 kcal/day
- Large adult (5-6kg): 240-290 kcal/day

|---|---|---|
| 낮은 활동도 | -20% | 168 kcal |
| 보통 활동 | 기본값 | 210 kcal |
| 높은 활동도 | +20% | 252 kcal |
(Baseline: 4kg Adult cat DER 210 kcal)

Always Consult Your Vet Before Reducing Calories
Weight loss in overweight cats requires great care. Rapid calorie reduction can cause "Hepatic Lipidosis" (fatty liver syndrome). Always reduce weight gradually under veterinary guidance.
