If you tease her with the mouse pointer on her chest or stomach she will purr !

I also got her to meow also, by rubbing her forehead with the pointer.
If you make a slow circle around her body, (anti-clockwise) not only will her head / eyes follow your pointer, but toward the top, her paw will go up, and when in front of her paws at the bottom, her foot comes out like she wants to play with your mouse pointer.
(Don't hold the mouse down, just move it).
