I like to make my mouses 'mouse biscuits'. It's a mixture of powdered rice and oats (baby food), wet baby food, and a mixture of rolled oats, dog food, and seeds. Then I just bake them in little clumps, and toss one into each of my mouse cages. 
You can also add egg to these, which is good for preggo mice.
