Vegetables mostly
Mice love vegetables, because they would eat vegetables in the wild. They especially love lettuce, carrots, celery and broccoli. You should be careful about any chemicals that are on the vegetables before you give them to your mice, as some chemicals can make them very ill. Don't feed your mice citrus fruits like tomatoes, oranges and lemons.
Not all the time. Mice are sort of like scavengers. they eat the dead corpse of animals that they find in the "wild" but they also eat vegetables so they're considered omnivores
grass
