Thanks all! Flattered to see all the love for this article here, it was a fun game.
Cute article Houston, that said the cats pictured do not appear to be enjoying themselves, at all.
Fair enough - we have more pics which my editor didn't use, and if you follow the link to the Dallas Morning News slideshow, there are some pretty happy cats. I guess when a cat turns 19 he never looks like he's enjoying himself...
