Why CaloriPet

Built on Science, Made for Pet Parents

Our tools are grounded in veterinary nutritional science — not guesswork or generic advice.

Vet-Informed Formulas

All calculations use AAFCO and NRC nutritional standards — the same frameworks veterinary nutritionists rely on every day.

No Data Collection

All calculations run directly in your browser. We don’t store, sell, or share your pet’s data. Your privacy is fully protected.

Transparent Methodology

Every calculator shows exactly which formula it uses and why — no black boxes. Understand the science behind your recommendations.

Free, Always

The core calculators will always be free. We’re supported by carefully chosen affiliate partnerships with trusted pet brands — never intrusive ads.
