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.
