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 - 隨着天氣越來越冷，小心使用防凍劑絕對是至關重要的；確保防凍劑安全地保存在你的棚子裏，並清理任何溢出物。防凍劑對貓咪的殺傷力很小，而且大多數防凍劑對貓咪（和狗）來說味道不錯，所以它們會繼續喫。
