Bird & Squirrel #1: Bird & Squirrel on the Run by James Burks (author and illustrator)

Squirrel is afraid of his own shadow. Bird doesn’t have a care in the world. And Cat wants to eat Bird and Squirrel. Of course, he’ll have to catch them first, and that’s not going to be easy. Join this trio as they head south for the winter in a hilarious road trip. But watch out! Cat is waiting around every bend, and he’s one pesky feline.
