Pet toxin

The text below is reproduced verbatim from the Pet Poison Helpline toxin page.

> Antifreeze is a broad term for chemicals that increase the freezing point of water.

> Pet animals are exposed to antifreeze by access to leaking vehicles, containers in garages and storage sheds, winterized RV plumbing including toilets, and improperly disposed vehicular waste fluids.

> While many antifreeze products contain ethylene glycol, not all products do, making it important to determine which type of antifreeze a pet may have ingested.

> Depending on the type of antifreeze, clinical signs of poisoning may include gastrointestinal distress, neurological disorientation, and organ failure.

> Signs are dependent upon the specific chemical contained in the antifreeze and the volume ingested; small volumes of the antifreeze ethylene glycol can lead to death if treatment is delayed after exposure.

> Contact your veterinarian or Pet Poison Helpline immediately if you suspect your pet ingested antifreeze.
