Which host is referenced as a host for cat fleas in the material?

• A. Cats
• B. Dogs
• C. Opossums
• D. All of the above

Answer: (D)

The main idea here is that cat fleas have a broad host range. They’re not limited to one species; they commonly feed on cats but will also infest dogs and other mammals, including wildlife such as opossums. If the material references cats, dogs, and opossums as hosts, it shows that fleas can live on multiple animals. Therefore, the best answer is All of the above, since each of those animals can serve as a host. This also helps explain why flea control often requires addressing multiple potential hosts and environments, not just one animal.
