YSK - As weather gets colder, it is absolutely vital you are careful with antifreeze; making sure it is kept safely in your shed and clean up any spills. Antifreeze kills cats in tiny amounts, and most taste good to kitties (and dogs) so they will continue eating it.

YSK - 随着天气越来越冷，小心使用防冻剂绝对是至关重要的；确保防冻剂安全地保存在你的棚子里，并清理任何溢出物。防冻剂对猫咪的杀伤力很小，而且大多数防冻剂对猫咪（和狗）来说味道不错，所以它们会继续吃。
