Read the following outline. Topic: Whether a dog or cat will be a better pet Paragraph topic 1: Friendliness Dogs are warm and friendly. Cats are standoffish and independent. Cats don’t make as much noise as barking dogs. Paragraph topic 2: Protection Most cats are not known to protect homes from intruders, and rarely will a “beware of cat” sign be displayed on a fence. Dogs are protective and bark to warn intruders to stay away. Paragraph topic 3: Care Cats are self-sufficient; they can take care of themselves as long as food is left out for them. Dogs need a lot of attention and care. They have to be let out or walked regularly, and they have to be watched—especially when they are puppies—so they don’t chew furniture.
