About PetFeedCalc

PetFeedCalc provides free, science-based feeding calculators to help pet owners determine the optimal nutrition for their dogs and cats.

Our Mission

We believe every pet deserves proper nutrition. Our calculators use veterinary-approved formulas including Resting Energy Requirement (RER) and Maintenance Energy Requirement (MER) calculations to give you accurate feeding recommendations.

How Our Calculators Work

Our tools are based on established veterinary nutrition science:

• RER Formula: 70 × (body weight in kg)^0.75 — the foundation for all calorie calculations
• Activity Multipliers: Adjustments based on age, activity level, and reproductive status
• Breed Considerations: Size-specific metabolic differences accounted for

Important Disclaimer

Our calculators provide general guidelines based on average nutritional requirements. Every pet is unique. Factors like health conditions, medications, and individual metabolism can affect dietary needs. Always consult with your veterinarian before making significant changes to your pet's diet.
