Waffles and Pancake: Planetary-Yum (Waffles and Pancake #1) by Drew Brockington

From Little, Brown Ink:

Inspired by his beloved CatStronauts series, Drew Brockington is going back in time to when everyone's favorite Catstronaut, Waffles, was a kitten! Fans of Narwhal and Jelly and Elephant & Piggie will love this fun, cat-tastic early graphic novel series.

One very special Saturday, Dad-Cat decides to take Waffles and his sister Pancake to the big city to go to the science museum! While they're there, the kittens see extraordinary things, like dino-cats, hairballs in 4D, and even the planetarium. But as the kittens learn about constellations and Neil Pawstrong, they get separated from Dad-Cat. Oh no!

Will the kittens be able to find their (possibly invisible) Dad-Cat? Or will they get stuck living in the museum and eating star tots and tuna melts fur-ever?! This early graphic novel series is chock-full of educational facts about space—perfect for young readers.
