Topic: deciding between a cat and a dog
paragraph topic 1: cat pros cats are self-sufficient; they can take care of themselves. cats also don’t make as much noise as barking dogs do.

paragraph topic 2: cat cons most cats are too independent. they aren’t known to discourage unwelcome guests and rarely does one see a “beware of cat” sign on a fence. they often bring dead birds and rodents inside.

paragraph topic 3: dog pros dogs are warm and friendly. they are protective and bark to warn intruders to stay away.

paragraph topic 4: dog cons dogs need a lot of attention and care. they have to be let outside or walked regularly and they have to be watched—especially when they are puppies—so they don’t chew the furniture.
