CatStronauts: Cosmic Clutter

CatStronauts #7

by Drew Brockington

In the seventh book in the hysterical CatStronauts graphic novel series, Major Meowser is in for a surprise! His space veteran dad-cat has just been recruited to join his next mission. But when the two can’t see eye to eye on who’s in charge, will their first mission together end up in cat-tastrophe?

It’s family day at CATSUP HQ, and Major Meowser is waiting for his dad-cat to make a BIG entrance. Anycat who’s anycat knows who Buck Meowser is—the first cat to ever orbit Earth. He’s a CatStronauts legend! Major's in for quite a shock, though, when CATSUP announces Buck is making a grand return, this time joining the CatStronauts on their mission to remove space junk from Earth’s orbit. Perfect time for father-son bonding, right? 

Well...Major and Buck can’t stop ruffling each other’s fur! But when the safety of their spacecraft is threatened, can these two put their paws together to make this mission a success?
 
Author-illustrator Drew Brockington tests the CatStronauts with everything he’s got—space litter, environmental peril, and of course, pawesome puns!

My kids (5 & 8) and I really love the CatStronauts series so we were so excited to get approved for ARC of this new installment. As always, this one was a hit with the kids. They love the action, the cute cats, the bright colors, the silliness, and the overall message about friendship and families.

From my perspective as a parent, it was a cute story with a lot of good messaging about family dynamics and conflict resolution. Some parts probably went over the kids' heads, but for the most part we really liked this one. Thanks to NetGalley and the publisher for the ARC!

My son loved the original books in this series many years ago, so I was excited to see another one was coming out. I was disappointed by several instances of "replacement cursing" where they were clearly trying to make puns in curse form. This is just not what children's literature needs; all it does is encourage kids to do it themselves.

I was given an ARC to read through NetGalley. My opinions are entirely my own.

I love cats. I love puns. I love a good cat-themed pun. This hit all those marks well!

CatStronauts: Cosmic Clutter was a fun little romp with a good message. I appreciated how it pointed out the importance of relationships, sustainable enterprising, and trusting in yourself while making me giggle at the same time. As a parent, I can't wait to share this one with my 8 year old!

Thanks to NetGalley and Little Brown Books for providing me with a free eARC in exchange for an honest review.

Our entire family loves these books, and we were all SO excited to have a new one out! This one answered almost all of my questions in such a delightful way, and also included my two sons’ favorite spittoo of the whole series. Well worth the wait! I very much hope there will be another one some day (I still need closure on Ava’s story)!

This engaging graphic novel is a lot of fun for space loving young readers. The illustrations are wonderful and compliment the story. Thanks to Net Galley for letting me read and review.

A great continuation of the story and some background information about Waffles and Pancake!
