Send questions, corrections, accessibility feedback and partnership notes to hx606383@gmail.com.

For a calculation or source issue, include the page URL, the inputs you used, the result you expected and a short explanation of the difference. For an accessibility or layout issue, include your browser, device and the step where it happened.

You do not need to send a pet's name, address, medical record or any other private information. Please do not use email for urgent health questions; contact a veterinarian instead.

We can review calculator logic, cited sources, broken links, page content and usability problems. Results are estimates, so a disagreement with a veterinarian or a different published model is useful context rather than proof that one number is universally right.
