In the notes:

In case you are wondering, cats apparently need regular maintenance, like cars. And, like an oil change, this juicing process can be done (I'm told) at home, preferably with the curtains drawn and a couple inches of sawdust laid down. That's right: you can wring out your own cat's asshole. This is the kind of helpful information you can expect when you visit Penny Arcade. Don't everybody run home at once.
