🐱Cat Food Calculator
A cat food calculator determines daily calorie needs based on body weight and life stage. Cats are obligate carnivores with specific nutritional requirements. Overfeeding is extremely common and contributes to feline obesity, diabetes, and joint problems.
💡
Tip: Cats naturally eat 10–15 small meals per day. Puzzle feeders and meal-sized portions rather than free-feeding help maintain healthy weight.
- 1Calculate Resting Energy Requirement (RER): 70 × (body weight in kg)^0.75
- 2Multiply RER by life stage factor: kitten ×2.5, neutered adult ×1.2, intact adult ×1.4, senior ×1.1
- 3Convert to food quantity: kcal target ÷ kcal per gram of food
4kg neutered adult cat=~230 kcal/day70 × 4^0.75 × 1.2 = ~230 kcal
4kg kitten=~480 kcal/dayKittens need twice the calories of adults
