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.

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)
