Booklist Reviews

When evil rats from outer space begin eating Earth's moon, the only answer is to blast a cat in a space suit up there to deal with them. Thus begins a hilarious series of episodic space adventures, colored by a host of silly characters who help or hinder First Cat on his way to confronting the villainous Rat King. Best buds Barnett and Harris have here adapted their inspiring "live cartoon" video series into a meaty graphic novel, and it's an obvious work of creative joy. Gags from the videos are successfully repeated on the page, and the jokes work on multiple levels: even when some of the more meta humor goes over the heads of less experienced readers, there's visual and tonal comedy in every panel. Harris' thick-lined cartoon artwork adds undeniable grandeur and beauty to the settings of an otherwise goofy affair, and the character design is endearing, especially the laconic First Cat ("Meow"), who ventures to the moon with all the air of Washington crossing the Delaware. A definite winner in the age of Dog Man. Grades 2-5. Copyright 2022 Booklist Reviews.

What began as an online storytelling experiment between Barnett and Harris during COVID-19 has been adapted into a graphic novel. This wacky space opera follows a crew of unlikely heroes on a mission to stop a horde of moon-eating rats. The cybernetically enhanced First Cat, along with a brave moon princess and friendly toenail-clipping robot, travel to the dark side of the moon, where they encounter a bloodthirsty baby pirate, a thieving team of disembodied hands, and a three-headed Rat King. The breakneck, stream-of-consciousness plot can be dizzying but never fails to be entertaining. Barnett's fast-paced dialogue, pleasing non sequiturs, and humorous wordplay (Oh my Uncle Tony's hot calzoney) are amplified by Harris's impressive illustrations. An invitingly simple thick crayon-like line is employed throughout the comic, from its cartoony imagery to panel borders to lettering. The surprisingly earnest themes of friendship and individual purpose combined with the absurd humor should resonate with this audience. Copyright 2023 Horn Book Guide Reviews.

Will extragalactic rats eat the moon? Can a cybernetic toenail clipper find a worthy purpose in the vast universe? Will the first feline astronaut ever get a slice of pizza? Read on. Reworked from the Live Cartoon series of homespun video shorts released on Instagram in 2020 but retaining that "we're making this up as we go" quality, the episodic tale begins with the electrifying discovery that our moon is being nibbled away. Off blast one strong, silent, furry hero—"Meow"—and a stowaway robot to our nearest celestial neighbor to hook up with the imperious Queen of the Moon and head toward the dark side, past challenges from pirates on the Sea of Tranquility and a sphinx with a riddle ("It weighs a ton, but floats on air. / It's bald but has a lot of hair." The answer? "Meow"). They endure multiple close but frustratingly glancing encounters with pizza and finally deliver the malign, multiheaded Rat King and its toothy armies to a suitable fate. Cue the massive pizza party! Aside from one pirate captain and a general back on Earth, the human and humanoid cast in Harris' loosely drawn cartoon panels, from the appropriately moon-faced queen on, is light skinned. Merch, music, and the original episodes are available on an associated website. Epic lunacy. (Graphic science fiction. 8-11) Copyright Kirkus 2022 Kirkus/BPI Communications. All rights reserved.

Publishers Weekly Reviews

Adapting the "Live Cartoon" series that shares this title's name, Barnett (John's Turn) and Harris (Have You Ever Seen a Flower?) replace innovative papercraft and DIY camerawork with an assured graphic novel collaboration. When rats from another galaxy begin devouring the moon, Earth's smartest scientists dispatch a cybernetically enhanced cat—the First Cat in Space—to deal with the threat. Accompanied by a guileless, toenail-clipping robot named LOZ 4000 and the proud Moon Queen, First Cat adventures across a madcap geography (frozen wastelands, violent seas, living forests) to confront the Rat King. An effective fluid panel structure and frequent perspective changes propel this fast-paced escapade from gag to gag in location after increasingly improbable location. Harris uses a thick, confident line to create an expansive cast of dynamic characters (mostly light-skinned) out of simple shapes, filled and shaded with textural colored pencil. In full, vivid color, the loose cartoon style exudes an infectious glee, flawlessly matching Barnett's freewheeling, absurdist humor and plotting. Includes sheet music to one of the original series' tunes, plus a link to a full collection of tracks. Ages 8–12. Agent: Steven Malk, Writers House. (May)

Gr 3–5—When moths, the ocean, and a wereduck—all things impacted by the moon—start exhibiting strange behaviors, a scientist working at an observatory notices something incredible: the moon is being eaten by intergalactic rats! When officials at the military headquarters in the Hexagon learn they only have three days to stop the rats or else the moon will be lost altogether, they prepare to send in Project 47: a cat enhanced with microchips in its brain, a cybernetic biotech space suit, and a penchant for pizza. Running gags that manage to stay fresh, clever panel-crossings, and fourth wall-breaking book references are all part of the charming humor of this online experience turned graphic novel. The art is simple but sophisticated, with a rough chalk texture giving it a childlike appearance. The dominant colors of black and cornflower blue are used to represent outer space, but other colors are present—notably warm reds, yellows, and oranges. Many of the characters are anthropomorphic animals; protagonist First Cat never speaks beyond saying "Meow," but meaning is mostly explained via context. Of the humans, there is a mixture of white and BIPOC representation; the General and the scientist appear to be Black. Footnotes are left for readers on where to find music from the story online. VERDICT Readers looking for the outer space high jinks and gentle humor of Brockington's Catstronauts and the imaginative and fantastical worldbuilding of Andrews's This Was Our Pact need look no further than this laugh-out-loud tale of the first cat in space.—Alea Perez
