Through tireless research, I have discovered additional cat facts which may be candidates for inclusion:
Outside of the CAT scan, cats have made almost no contributions to modern medicine.
In ancient Egypt, the cat-god Horus watched over all cats.
The word "catastrophe" has no etymological relationship to the word "cat".
Many cats appear black in low light, suffering a -2 modifier to luck rolls.
The popular trivia game "World of Warcraft" features a race of cat people called the Khajiit.
We could make clicking the item (or any other item) pop up a dialog now fairly easily if you want -- not sure if that's the best direction to take the grand future of Cat Facts, but it's on the table as an easy technical thing if it makes sense here or elsewhere.
