Please keep this out of reach of your animals.
Most commercial antifreeze contains ethylene glycol, a rapid acting and lethal toxin.
The toxin can cause sudden neurological signs such as delirium and seizures. Prompt diagnosis and treatment shortly after the ingestion of anti freeze by the pet may result in reversal before the more advanced stages of the poisoning. Within a short period of time the toxicity proceeds to permanently damage the kidneys and treatment at this stage is usually not successful. If you come across an antifreeze spillage in driveway or garage, wash it away thoroughly and cover area with kitty litter and then dispose of properly. They actually make non toxic anti freeze now, which contains propylene glycol.
