Antifreeze ​Antifreeze is a common poison that can make dogs and cats incredibly unwell or die. It is a very sweet substance and both dogs and cats (in particular) seem to really like the taste of it.
The active substance in antifreeze is Ethylene Glycol and this is incredibly toxic to all animals. Even a few licks can cause a fatal and rapid kidney failure, which unless diagnosed and treated incredibly quickly, is usually fatal.
If you have antifreeze at home. Keep it correctly sealed and out of the reach of your pets. If you refill your car, please ensure that any old liquid is disposed of correctly and if there are any spillages then they should be soaked up and and remains thoroughly rinsed with copious amounts of water.
