Angus and the Cat by Marjorie Flack

From Caldecott Honor-winning children's author and illustrator Marjorie Flack comes an adventure featuring her beloved Scottish terrier who must learn to get along with a new member of the family in Angus and the Cat. Angus's world is turned upside down when a feline joins the household. She's eating his food, napping in his favorite sun-filled places, and jumping out of reach whenever he chases her. Peace and quiet resumes when the cat disappears, but Angus finds himself missing his new friend.
