Cat fleas can be found on which animals?

• A. Cats only
• B. Dogs
• C. Cats, dogs and opossums
• D. Humans

Answer: (C)

Cat fleas have a broad host range because they are blood-feeding parasites that move between animals that share the same environment. They commonly live on cats and dogs, and they can also be found on wildlife such as opossums that visit yards or shelters. Because the question asks where fleas can be found, including both pets and wildlife, the option that lists cats, dogs, and opossums best reflects their host range. The other options are too limited—cats only excludes dogs and wildlife; dogs excludes cats and wildlife; humans can be bitten but aren’t typically a sustained host for fleas.
