Vegetables can be consumed in many forms and still count toward the daily serving requirement. This includes 100 percent vegetable juice and raw, cooked, fresh, frozen or canned vegetables. One-half cup of vegetable juice or most raw vegetables equals one serving.
Pet mice will eat most kinds of vegetables, but they tend to enjoy crunchy ones more. Vegetables such as broccoli, carrots and celery contain a balance of vitamins, minerals and carbohydrates that are essential to keeping your pet mouse healthy. A piece of apple also serves as a healthy treat.
Mice are omnivores and eat a variety of foods preferring seeds, grains and nuts. They require only about l/10 ounce of food each day and can live without access to fresh water if the solid food they eat is somewhat moist.
