Catch the cat

Here's a cute little Flash game that is both surprisingly solvable and surprisingly challenging.  Very bare-bones - you have a grid of circles and click them to keep a cat from escaping the grid.

It would be a good AI target, actually.  I think this may be a case where it would be interesting to explore simple semantic structures of some kind (grouping areas into some kind of cage element or something). I'm not sure.  But it would be interesting to explore.
