If your pet is hurt or ill right now, ring your vet or the nearest emergency vet instead of doing this, and in a fire get out and call 911 in the US or 999 in the UK. Otherwise, ring your own vet or look at its website or phone message, and ask who answers at night and where that clinic is. Save its name, number and address in your phone as “Vet at night”. Then ask one person you trust if they would look after your pet if you were in hospital, and write their name and number on a sheet by the door.
If your pet may have eaten or touched something harmful, you can call and talk with a veterinary toxicology expert who helps you work out the risk and what to do next.
