About PetPawCalc

PetPawCalc is a free resource for pet owners who want clear, reliable answers — without wading through ads, paywalls, or vague advice.

We build calculators and guides for everyday pet care questions: How old is my dog in human years? How many calories should my cat eat? What does owning a pet actually cost per year?

Our Approach

Every tool on PetPawCalc is built on established veterinary research and published guidelines. We cite our sources and clearly state where estimates are approximate. We don't make medical diagnoses — that's your vet's job — but we help you show up to that appointment better informed.

Who Made This

PetPawCalc is an independent project built by a pet owner who got frustrated searching for simple answers and finding mostly noise. No corporate backing, no sponsored content — just useful tools.

Always Consult Your Vet

Our tools are for informational purposes only. Please always consult a licensed veterinarian for medical decisions about your pet. No calculator replaces professional care.
