Every year more than ten thousand dogs and cats are accidentally poisoned with automotive antifreeze. This is the most common cause of poisoning of dogs and cats in the U.S. The toxic ingredient in antifreeze, ethylene glycol, is also it's major component. It makes up 95 per cent of the product, therefore, it only takes a small amount of antifreeze to poison a dog or cat. One or two teaspoons full of antifreeze will poison a cat and three tablespoons is enough to kill a medium size dog. Ethylene glycol is sweet and quite tasty to dogs and cats and they will actively seek it out.
