Step Two: These three cat toys! I don't know about your cat, but mine fetches. And I mean that literally. Sometimes I think she's a dog with how fast she'll run out, grab whatever it is, and bring it back. So yeah. I leave these little guys laying around her so she can let me know when she wants to play.
