Fresh off of their heroic mission to save the world, the CatStronauts—Major Meowser, Pom Pom, Blanket and Waffles—are taking a well deserved victory lap. Parades and fancy awards dinners are the new norm! But around the world, other cat space programs are watching—in particular the CosmoCats, the first cats to go to space! With national pride and scientific research on the line, the world's space programs rush to be the first cats to Mars, and the CatStronauts are starting months behind! Can they catch up and prove their first mission was no fluke? In this graphic novel, debut author/illustrator Drew Brockington takes the CatStronauts further than they've every gone, adding in mounds of jokes, charm, science, and enough yarn and scratching posts for everyone!
