Read the following introduction from an essay. It's an age-old debate: Cat or dog? Which makes the better pet? According to the American Humane Association, there are more cats (64.1 million) than dogs (63.8 million) in the US. But because people often own more than one cat, dog households outnumber cat households. Because dogs are loyal, show more affection, and are easier to teach, they make better pets than cats.
