We started this when she was a kitten, and I would line up a few kitty treats on the edge of my desk and she would knock them off and eat them. I've tried to teach Emma this, but she just dives in a gobbles every one of the treats from the shelf . . . so it's our little secret game. We can only play on the sly or when Emma is outside . . . shhhhh!
P.S. There are 14 Photobook volumes on the shelf just above Squeak's paw. I have made a few more as gifts that I don't have a copy of, but so far that's my stash!
