I'm posting this after reading IfAtFirstUDontSucceeds thread on the loss of her beloved cat to anti-freeze poisoning.
Anti-freeze is sweet tasting and in a literal sense, fatally attractive to cats, dogs and other animals. Horrifically there have been cases of deliberate poisonings as well as accidental ones where animals have ingested spilt anti-freeze. The "Blue Death" campaign was started by a woman who lost her own cat to anti-freeze poisoning and the site has news, information, suggested wording for MP letters, a link to the Facebook page and a petition for safer anti-freeze, which looks as if it could do with some support.
