What are the common foods for pet mice?

Commercially prepared pellets or a mixture of grain and seeds can be used. Commercial feeds come in a hard
pellet form and contain all necessary nutrients. The hard pellet is also beneficial in keeping the continuously
growing front incisors worn down.
A ration can be purchased or prepared using corn, oats, and wheat and then adding small amounts of millet,
barley, and buckwheat. Small amounts of oily seeds are good for adding shine to the hair coat. Commercially
prepared feeds are recommended because the amounts and ingredients are chosen to ensure that the
diet is complete and balanced.
In feeding a ration, various greens and vegetables can be added. Fresh grass, lettuce, dandelions, carrots,
apples, dates, and raisins can be added. Clean, fresh hay can supplement the diet and will also serve as a nesting
material.
