Cat got your tongue

I know when someone can't or won't speak someone would say: "What's the matter?" "Cat got your tongue"?
Where did this come from!?

"Has the cat got your tongue? Why don't you speak? Your silence is suspicious. The saying originated in the mid-nineteenth century and was used when addressing a child who refused to answer a parent's questions after some mischief..."
