Are Mice Really Crazy About Cheese?

Introduction

The stereotype of mice having an insatiable craving for cheese has been ingrained in popular culture, from Shakespearean tales to animated shows like Tom and Jerry. However, do mice truly have a fondness for cheese?

Contrary to Popular Belief

Contrary to popular belief, mice do not actually have a strong affinity for cheese. In fact, some types of cheeses emit odors that repel mice due to their acute sense of smell. Researchers at Manchester Metropolitan University in the UK have discovered that while mice can consume a variety of foods from meat to paper, they are more drawn to sugary options like fruits, cereals, and even chocolate. Their dietary preferences are rooted in their natural instincts, as they historically consumed foods similar to what they currently prefer, prior to the invention of cheese around 10,000 years ago.

Natural Diet of Mice

Mice are omnivores with a diverse diet that includes seeds, grains, fruits, berries, insects, worms, snails, and plant waste. Their dietary habits vary depending on the availability of food sources in their environment.

Cheese-Testing Experiment

In a study conducted on the BBC show Winterwatch, researchers tested mice's preference for cheese by presenting them with three options: cheddar cheese, peanuts, and grapes. Surprisingly, the mice consistently chose peanuts over cheese, debunking the notion that mice have a strong affinity for cheese.

Origins of the Myth

The misconception that mice love cheese likely stems from historical practices of food storage in the Middle Ages. With limited refrigeration options, cheese was often left exposed on shelves, making it an easy target for hungry mice. The visible bite marks on the cheese might have led to the misconception that mice have a preference for cheese.
