Calorie Cats Calculator

Use the ideal (target) weight when calculating for weight loss.
Use a factor your veterinarian gave you instead of the published range.

Worked out from Pet Nutrition Alliance - Calculating Calories Based on Pet Needs (RER = 70 x BWkg^0.75; Table 1 MER factors) and 1 other source.
These factors are estimates: the Pet Nutrition Alliance notes individual animals can vary by as much as 50% from the predicted value, so adjust to maintain an ideal body condition score.
Educational estimate only. The published MER factors are starting points - individual animals vary by as much as 50% - and a veterinarian should set the feeding plan, especially for weight loss, growth, gestation or illness.

How this is worked out

4 steps
  1. Body weight = 4.500 kg
  2. RER = 70 x 4.500^0.75 = 70 x 3.089651 = 216.28 kcal/day
  3. MER = 1.2 x RER (Neutered adult, cat) = 259.53 kcal/day
  4. No food energy density supplied, so no portion was computed.
