I speak baby, as I mentioned before, and pig latin, and a little English...... but if I spoke cat I would tell Boo:
That's great that you know how to hunt!! Good for you! And you can hunt just about anything, WOW!! But, really, I appreciate that you like to show me what you've done.... but really, you don't have to. I know you can do it and that's good enough. Now will you take the little dead birdie off the porch and go put it somewhere else?
