The four digital issues were published by Astro Comix (Dan Parent & Fernando Ruiz's company; http://www.astrocomix.com/), and originally this book was going to be published by Astro Comix too. However, by the time the book was ready for publication, Parent and Ruiz had signed with Charterhouse Comics to publish the four issues of Die Kitty Die in physical form and distribute them to comic book stores, so Charterhouse published this book too.
