All Creatures Great and Cheap

All Creatures Great and Cheap is a pet store inside the Springfield Mall. They have a sign reading "You Pet It, You Bought It." It is home to a bird Homer likes arguing with about crackers.

Behind the Laughter
The name of the store is a pun on All Creatures Great and Small, a novel by English veterinarian. It is also a pun on the song of the same name which is about animals.
