Quick answers to the questions every pet parent asks. Free, no sign-up.

The internet is loud about pets. We’re trying to be useful.

Grounded in the guidelines

Our calculators use the formulas vets actually use — Merck for feeding, AAHA/AAFP for vaccines, the 2020 epigenetic clock for dog age. Every source is named.

No fear-selling

We don’t scare you into a purchase. Tools run free in your browser, advice is honest about its limits, and “ask your vet” means ask your vet.

We tell you how we earn

When we recommend insurance or food, some links earn us a commission — and we say so plainly. It never bends what the tools tell you.
