The new book from The Oatmeal, the comic Website by Matthew Inman, How to Tell If Your Cat Is Plotting to Kill You (Andrews McMeel Publishing), was opened up for preorders on August 7 and immediately went to #12 on the Amazon bestseller list, even though it doesn't release until October 9. The Oatmeal has a big following and generates $500,000 a year in revenue, Inman told the Guardian. Inman's first book, 5 Very Good Reasons to Punch a Dolphin in the Mouth, has sold modestly since its 2011 publication.
