My friend Damon writes from Memphis:

This afternoon I was a judge at the Shelby County Science Fair. The best poster that I saw – (we only judged 12 out of like 300) “Do cats always eat the most expensive catfood regardless of flavor”. The experiment was to buy three different brands of cat food, same flavors (chicken, fish, beef) and feed them four different cats to see which ones they preferred. Conclusion: Cats eat the cheapest food. Go figure.
