Daily Calorie & Portion Calculator

Estimate how many calories your pet needs today, not a guess from the bag.

This estimate uses the standard veterinary RER/MER formula, but individual needs can vary by as much as 50% from the calculated value — treat this as a starting point, then adjust based on your pet's actual body condition, and check with your vet for weight-management or medical diets.
