Veterinary notes and prevention
Ethylene glycol metabolites cause irreversible kidney failure. An antidote exists but the treatment window is very short, especially in cats.
Prepare the information your vet needs
- For Antifreeze (ethylene glycol), report the exposure route: Licking spills from driveways and garages, or drinking from contaminated puddles. Tell the clinic the time, possible amount and your pet's species and approximate weight.
- Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
- Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
- Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
