At that time, if they find any single tiny mouse, they will go for it and eat it quickly. Though it is not a portion of good food for the chipmunks, they will eat mice in that way.


The chipmunks and other rodents like squirrels can eat the meat of the insects. If they fail to get any food source or nut, they will eat the insects around them. It is a new eating habit for the chipmunks that helps them eat the mice.

So, mice are not the first meat they eat; instead, they eat mostly insects and survive when they don’t find anything else to eat. So, it’s not a permanent food source for the chipmunks, only for the time being.

Mice Size:

Normally, mice, are in small sizes. They fear pretty much every big rodent. Since they are small, all other rodents can quickly eat them when they can’t find any other food.

But adult mice are big enough. No rodents can chase the adult mice and can’t eat them either. So, mice sizes are also a vital factor here.

Field mice:

Chipmunks cannot eat the field mice. In fact, they are not fond of any adult mice either. Field mice or house mice are pretty much the same. They are all adults and bigger as well.

Moreover, the chipmunks don’t like to chase the big or adult mice, even though they don’t chase either. So, chipmunks don’t eat the field mice.
