Quick: How to Tell If Your Cat is Plotting to Kill You by The Oatmeal (Matthew Inman), 2012, 9781449410247.
Online comic strip published in print. Cat cartoons. I often say how cats are evil so I brought this home for the children to learn from. I had to read it first to make check for inappropriate content and did give some warnings and explanations of some gags.
A small number of single panel comics. Most comics are longer with many panels and long jokes.
Excessive Ear flicking
What appears to be going on: Kittens have twitchy ears.
What's really going on: Kittens are sending and receiving messages of doom across the globe. "Tomorrow at 0800 hours humanity will fall."
