Hark! A Vagrant comics, Matthew Inman's (aka The Oatmeal) How to Tell If Your Cat is Plotting to Kill You began life as an internet comic series.
The similarities stop there.
Beaton's cartooning is original looking, while Inman's looks generic. I don't know why it bothered me so much this time, perhaps because it was a whole book's worth, but I really started to resent the lazy cartooning of most internet comics. Everything is just a series of simple circles with no detail. (You can see what I mean here.)
And I guess I'd be forgiving if it was at least funny, but the title's the funniest part. The title also isn't an accurate summary of the book. Cats plotting to kill their owners is but a small section, the rest is just random cat cartoons. Mildly amusing observations that most of us cat lovers have made time and time again. I did find myself smiling at a bit where a human and a cat switched roles, but the hilarity of seeing a person act as a cat has also been played out and done better.
