How guides are written
Each guide starts with a short answer, then explains it and links the sources.
We summarize guidelines and public-health pages. We do not invent statistics, reviews or ratings.
Where a source gives a range or says to ask a vet, we say that instead of giving a single rule.
Phone numbers and fees for poison hotlines were checked against the services’ own pages in October 2026 and can change.
The content was prepared and checked against the cited sources in October 2026. It has not yet been individually reviewed by a licensed veterinarian. Treat it as a starting point for the conversation with your own vet.
