My sister (parents' cat) is great at communicating. She'll get your attention and then lead you to whatever she wants. The door to go outside, the food drawer for treats, the bathtub for running water, and to her toys if she wants to play.

Sometimes she likes to steal my dad's office chair; for that she'll lead him out of the room as if she wanted something else and then run back in to claim the now-vacant chair. Or she just jumps up and wedges him off :D
