From my Inbox: "One issue that I've never seen addressed is that antifreeze is lethal for pets (and humans). There's never been any activity by the industry to add something to make it taste bad."
Indeed, because of the toxicity of ethylene glycol, there have been numerous articles warning about its use near pets, including the one linked in the title, by PetMD.com for About.com. Although the industry may not have changed its standards, a number of state legislatures have passed laws requiring the addition of a "bittering agent (most commonly, denatonium benzoate)", according to this article from the American Veterinary Medical Association. An alternate product, with propylene glycol, is odorless and tasteless, so not as attractive, although it is still toxic. My original blog:
Your garage can be a hotbed of danger for your cats, particularly in the winter season when we use antifreeze containing ethylene glycol, which is poisonous when ingested. cats have an unaccountable sweet tooth, and ethylene glycol is very sweet to the taste.
Antifreeze poisoning is one of the most common forms of poisoning in small animals, and this is because it is so commonly found in households. Antifreeze poisoning typically happens when antifreeze drips from a car's radiator, where it is then licked off the ground and ingested by an animal. Your cat may also come into contact with antifreeze that has been added to a toilet bowl. This occurs in homes where the residents will use antifreeze during the cold months to "winterize" their pipes. Even if you do not take this action in your own home, it is something to be aware of when visiting other homes, or when vacationing at a winter residence. Please don't take chances with your cats' lives. Read this article by PetMD.com for About.com for more information on the symtoms, diagnosis, and treatment of antifreeze poisoning in cats.
