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 nocturnal, meaning they like to sleep during the day. This is why pet mice or house mice can be heard playing or foraging during the night. Most wild mice are timid toward humans and other animals, but they are very social with other mice.
