Here's a fun thing to try. If you have one of those soft-sided folding laundry baskets, try inverting on the floor some day and see if your kitty will take an interest. Put a treat under it if you like. Our cat Baxter loves to dive under things (bags, boxes, papers), so this was a natural for him.
For Baxter, laundry day, is ambush day. He loves the dual purpose material. He can see through it, but still feel like he's hiding. It's hilarious to watch him lie in wait until an unsuspecting friend walks by. Then it's all over for his "victim".
