Grumpy Cat / Garfield #1

This crossover one-shot brings together two of pop culture's most famously cantankerous felines: Grumpy Cat and Garfield. Written by Mark Evanier with art by various creators, the story pits the perpetually displeased internet sensation against the lasagna-loving comic strip icon in a battle of wits and grumpiness. Published by Dynamite Entertainment in 2017, this collection offers a humorous, meta take on both characters' trademark attitudes.
