I just want to mention that the cat-related example of the author's CatAttack method (table 2) changes the answer from 8 to, of course, 9.

Unfortunately, this is, if I'm not mistaken, in fact the only cat-related CatAttack in the paper, the other methods being financial advice and a red herring. I was eapecting more cat facts, but instead I remain thoroughly disappointed and factless.
