What is the primary food that house mice typically feed on?

House mice primarily feed on cereal grains due to their natural dietary preferences and nutritional needs. In the wild, these mice are granivorous, meaning their diets predominantly consist of seeds and grains, which provide them with the carbohydrates, proteins, and fats essential for their energy and growth. Cereal grains are not only readily available in agricultural areas but also constitute a significant part of human food supplies, making them accessible to house mice living in or near human habitats.

While house mice can consume a variety of foods, including some of the options listed, cereal grains remain their primary food source. The mice's natural instinct drives them to seek out grains as they are nutrient-dense and support their survival needs effectively.
