Which rodent easily adapts to life with people?

• A. Norway rat
• B. Squirrels
• C. House mouse
• D. Chipmunks

Answer: (C)

When a rodent lives closely with people, it’s because it can exploit our food sources and shelter. The house mouse fits this pattern best. It’s tiny and can squeeze through very small gaps, so it readily moves into homes, barns, and other buildings. Its diet is highly flexible, taking a wide range of foods found in human settings, from crumbs to stored grains. Most importantly, it reproduces quickly, so once a population establishes itself, it can grow rapidly. That combination of easy access, adaptable diet, and fast reproduction makes the house mouse the species most likely to thrive alongside people. Squirrels and chipmunks rely more on outdoor habitats like trees and burrows and are less inclined to colonize indoor spaces, while Norway rats also adapt to human environments but are not as emblematic of easy life with people as the house mouse.
