Sources and method
Where every number comes from, how we check it, and how to report a mistake.
Every page with a number has its sources at the bottom, with the date we checked them. The rules we follow:
- Only sources you can cite: veterinary guidelines (WSAVA, ESCCAP, AAHA, AVMA), veterinary manuals (Merck), animal welfare charities (ASPCA, PDSA, RSPCA, International Cat Care), peer-reviewed studies, official breed standards (FCI).
- Before using a page, we read its footer: some sites forbid rewriting their content with artificial intelligence. We don’t use them (for example the VCA “know-your-pet” pages).
- Our own words: from the sources we take facts and numbers, never sentences.
- No number without a source. If a source can’t be read, its number doesn’t go on the site.
- Never a diagnosis, a dose or a product name. Emergency tools never say “it’s nothing”: they say who to call.
- Mistakes: write to me and I fix them within 48 hours.
