The primary food preference for the Norway rat is indeed meat, fish, and garbage. Norway rats are known for their opportunistic feeding habits, which means they will consume a wide variety of food sources based on availability. Their natural diet in the wild often includes insects, fish, and small animals, but in urban environments, they tend to scavenge for food, leading to a reliance on discarded food items, including garbage.

This adaptability to an omnivorous diet allows them to thrive in diverse environments, particularly in areas where human habitation provides ample food sources. While they may eat fruits, vegetables, grains, and seeds, these do not constitute their primary sources of nutrition. Instead, their preference for rich protein sources and waste products reflects their ability to exploit available food and survive in various conditions.
