How does the diet of a Norway rat differ from that of a house mouse?

• A. Prefers grains exclusively
• B. Prefers meat and fish
• C. Prefers fruits and vegetables
• D. Has no dietary preferences

Answer: (B)

The diet of a Norway rat is characterized by a preference for meat and fish, which sets it apart from the diet of a house mouse. Norway rats are omnivorous and consume a wide variety of foods, but they show a particular inclination towards high-protein sources, including meat and fish. This preference is significant in their natural behavior and survival, as protein-rich diets can support their rapid growth and energy needs. In contrast, house mice tend to favor grains, seeds, fruits, and vegetables, reflecting their feeding habits in more agricultural and human-influenced environments. This difference in dietary preferences is crucial for pest management strategies, as understanding what attracts each rodent species can influence control measures. Recognizing that Norway rats are drawn to and thrive on protein sources informs pest control operators about effective bait selection and placement to manage these rodents effectively.
