Most pet shops sell mixes specifically designed for mice or small rodents. These usually consist of grains, seeds, pellets, biscuit and dried vegetables.

There are also rodent or mouse pellets sold in some stores. These are compressed food pellets and although they are designed to meet a mouse's nutritional requirements they do not give the mouse any variety. Rodent or mouse pellets with some basic mouse mix will also provide an adequate main diet.

Food mixes specifically designed for other animals should not be given as these may not be suitable to meet your mouse's dietary requirements and may even harm your mouse.

Mouse mix does not perish quickly and so may be stored for some time in dry conditions without problem.

Any changes in diet, even changing to a different mouse mix, should be made gradually as a sudden change in diet can cause your mouse to become ill.

Mice should be fed a basic mouse mix as the main part of their diet and this can be supplemented with other treats.
