Are Mice Omnivores, Carnivores, Or Herbivores?

Mice invasion is a household plague that is as common as bug invasion. Mice destroy anything from food to non-food items. They have a thing for papers and this can be upsetting. Besides these, mice also eat plants and animals.

All animals fall under at least one of the three major feeding diets: omnivore, carnivore, or herbivore.

Herbivores feed on plants, carnivores feed on flesh, and omnivores eat a combination of plants and flesh. Mice, the focus of this article, seem to shuffle all three worlds.

Read on to find out whether mice are omnivores, carnivores, or herbivores.

Are mice omnivores, carnivores or herbivores?

Mice are omnivores. These creatures feed on both plants and animals. Mice are opportunistic eaters; one of the reasons why they are omnivorous.

What do mice eat?

Mice eat almost anything from food to non-food items. Some of the things mice eat include seeds, grains, meats, nuts, berries, leftovers, and paper.

Why do mice love cheese?

Contrary to popular belief and what you watched in the toons as kids, mice do not love cheese.

As said earlier, mice are opportunistic eaters; they will eat whatever they find available and are food-worthy.

Mice adopted eating cheese because their favorites, grains, and other sweet food items were stored high up beyond their reach.

The cheese was stored on shelves and it was easier for them to reach it. So, it became a meal. If you gave a mouse the chance to choose between cheese and grains, it will go for the grains instead.

Are mice producers or consumers?

Mice are consumers. They are one of the secondary consumers. They consume plants (producers) and smaller animals to survive.

Where do mice belong on the food pyramid?

On the food pyramid, mice belong to the consumers’ trophic level.

They are both primary and secondary consumers because they feed on producers (plants) and some small animals that also feed on plants.

Do mice prey on other animals?

Yes, they do. Mice eat animals that are smaller than them. These animals include centipedes, beetles, grasshoppers, caterpillars, snails, worms, slugs, and cockroaches.

What animals are mice prey to?

Mice are prey to dogs, owls, snakes, skunks, cats, eagles, hawks, herons, crows, lizards, foxes, wolves, and jackals.

Bigger cats like lions and tigers eat mice as smaller meals. But, there are not so many mice in the wild. They rather live in houses and stores because of these predators.

Do mice have any benefits to the ecosystem?

Mice are a nuisance to household items, but they have proven to have valuable uses in the ecosystem. Their position on the food chain is beneficial to the ecosystem.

Mice that prey on insects and their eggs help to reduce their population and infestation. Mice are also prey to cats and snakes.

The population of mouse predators is directly proportional to the population of mice. The more or fewer the mice, the more or fewer the predators.

Furthermore, mice are good soil aerators. Their movement in the soil helps to mix it with oxygen and water, thereby enriching the soil. Mice can also help reduce flooding via the tunnels they create on the earth as they move around.

In addition, they eat up any crop pests they find in the soil, thereby controlling pests and diseases.


Can mice be classified as heterotrophs or autotrophs?

Mice are heterotrophs, just like every other animal.

Animals cannot produce their food, a major characteristic of autotrophs. Plants and algae, on the other hand, are autotrophs.

Can you breed mice at home?

Yes, you can. With proper knowledge and maintenance, you can breed house mice and keep them away from your food items and useful materials.

Can mice bite humans?

Yes, they can. Mice are not very prone to biting, but they will if they feel threatened. This can happen when you are trying to hold or kill them.


Mice are omnivores. They are best described as opportunistic eaters. In essence, they eat whatever they find food-worthy at the time. An example is your files and papers, leather materials, and plastics.

Most importantly, mice should not be tolerated in the house, especially in cooking and eating areas. If you find any around your house, look for ways to get rid of them before they procreate and multiply.
