Notice: Mice collect food and store it in their nests for the upcoming winter season. They don't hibernate, but if they don't have enough to eat, they hibernate to reduce energy expenditure.

Other foods

In addition to food and animal feed, a mouse can also feed on cellulosic materials such as cardboard and wood. She does this when nothing else is available but the body is craving food. This allows her to stay alive for a few days and escape starvation without additional food or plant parts.

Notice: Chewed plastic objects are also often discovered – especially bags. This is usually not due to hunger. They either try to gain access to the contents by gnawing or they collect the fibers to build a nest. They nibble on cables, metals and concrete only to shorten their teeth.

frequently asked Questions

What do baby mice eat?

Mice are mammals. The baby mice are fed breast milk until their teeth are formed. This is the case from around three weeks of age. Then they are usually able to bite, slowly leave the nest and start looking for food on their own. Orphaned babies are fed with special rearing milk for kittens in sanctuaries. You can buy them in any well-stocked garden and pet store. You too can use it to raise babies if necessary.

Why are there so many mice in urban areas?

Cities provide an ideal habitat for mice and rats. They are particularly attracted to the rotten smell of food. This is mainly due to rubbish bins and containers. In densely populated areas, where, for example, residents of multi-family houses with numerous residential units have to dispose of their waste, mice can hardly be avoided. Here they will find more than enough food.

What is the difference between mice and rats when it comes to eating?

Rats chop up hard foods while mice tend to grind them up. There are no significant differences in the choice of food, except that rats can eat correspondingly larger foods due to their larger size. This even includes little mice.

What shouldn't be given to mice when housekeeping?

Above all, sugary food such as chocolate and sweetened cornflakes quickly leads to obesity in a mouse, from which it dies quickly. But also fresh legumes such as peas, beans and lentils, aubergines due to the toxin solanine, any type of cabbage and spicy foods such as chips are safe for mice Keeping pets taboo. High-fat food such as potatoes fried in oil or deep-fried French fries can also significantly shorten the life of a mouse.
