Multimammate Mice Diet

Multimmate mice need more protein in their diet than fancy mice, and can have a wider range of tastes. Many commercially available mouse foods include a lot of 'filler' items that are not high in nutritional value and so ideally you should try to make the mouse seed mix yourself; it is worth noting that different mice thrive on different items so you may find that your specific line of mice needs less fat or more grains that other strains. If you are ever in doubt of a foods suitability simply check online at a reputable source before feeding it.


Should always be available and changed daily. A bowl or bottle is fine for this, if using the latter just keep a careful eye on them as they can get clogged. Multimammate mice do chew plastic, so keep bottles lined up to prevent any chewing.

Seed mix

A good base mix for Multimammate mice is rat muesli, crushed oats, barley, porridge oats, various millets and grains can be added in various quantities.

A small amount of fennel seed added to the seed mix can reduce the urine smell from your mice.


Fruit and vegetables such as apple, banana, blueberries, papaya, tomato, broccoli, carrots, peas, sweetcorn, curly kale and sweet potato.

Foods that are high in water content should be given sparingly due to the diarrhoea risk. Items like watermelon and cucumber can be added to a mouse carrier during a long journey where other water sources cannot be given.


Protein can be given on a semi-regular basis, items such as mealworms, cheese, monkeynuts and scrambled egg. If you are keeping your Multimammate mice together with normal fancy mice, then some protein items should be fed separately as they need a higher level of this in their diet than normal fancy mice.


Sunflower seeds, pumpkin seeds, mealworms, cooked soya beans (thought to reduce the likelihood of tumours), stale or toasted wholemeal bread as well as pet-shop treats.
