Thousands of domestic, stray and wild animals are being killed from the toxic ingredients of antifreeze. To the animals, this is just water as they cannot smell or taste the difference. 

I myself have lost a cat to antifreeze and it is a horrible sight. They have to suffer in slot of pain before it kills them. I have also witnessed others who have lost pets in the same manner.

Whilst it could be impossible to completely ban antifreeze, it is possible to add a bittering agent to put off animals to not drink it. Animals shouldn't have to suffer in so much pain because of this substance.
