Hey, @bashadow.

It's always interesting to me how some things can be shrouded in mystery or legend when it comes to their origins. Apparently, no one was around to right these things down: First use of 'cat got your tongue' occurred to day...

Or maybe that's all been lost to time too. So basically, the first two options were getting beaten by a cat o'nine tails, very, very painful to the point of not being able to speak (thus the saying), or Egyptian cats and liars and blasphemers. Take your pick, I guess. :)

Pass the emu, mate. I could see that happening. :)
