cat got one's tongue

cat got one's tongue idiom
A comment made when someone is unaccountably or unusually quiet, as in We haven't heard from you all morning—has the cat got your tongue? Often put as a question, this term originally was used mainly with a child who did something wrong and refused to answer any questions. Today it is used more generally to ask anyone to speak. [Mid-1800s]
