The "D: According to Toni, 25% of their cats and dogs are undoubtedly purebreds" sentence supports the author's reason. A purebred pet needs much cost related to its breeding process. According to the "A Cat is not A Can of Soup" essay, the shelter has 25% of purebred pet, so, you can minimize the cost for the breeding process if you take the pet from the shelter.
