What do you feed pet mice?
Well, seeing as how I have some pet mice myself, I know you can get some mouse seed mixture at your local pet store. If you don't want to spend a lot of money, then take some bird seed and give them that. You can also give them some washed and cut fruit & veggies to balance their diet. Some dog treats make good chew toys, too! My mice love to chew on their dog treats. Hope this helps.
