Do you have to read CatStronauts in order?

Each book is its own mission, so a child can start almost anywhere. The first four are the best place to begin because they set up the crew and the space agency, and the later ones refer back to them. After a long gap in the 2020s there are now eight books.

What age is CatStronauts for?

Six to ten is the publisher's age for the books, not a reading level. The pictures carry most of the story and the jokes are quick, so younger children can follow it read aloud, while older children can enjoy the space ideas. Peabody's own lists put it at about 6 to 10. We don't print reading-level scores: they belong to the companies that make them.
