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.
What do they eat? Deer mice are omnivorous. They eat a wide variety of plant and animal matter depending on what is available, including insects and other invertebrates, seeds, fruits, flowers, nuts, and other plant products. Deer mice sometimes eat their own feces, a practice called coprophagy.
