Brief SummaryRead full entry
DescriptionMeadow Jumping Mice have very long tails and very large feet. They are most common in grassy or weedy fields, where they use runways made by other rodents. If they are frightened, they may creep away through the grass, or make a series of short jumps. They have to put on about six grams of fat in the fall, because they burn about a gram a month in their six months of hibernation. Jumping Mice have litters of 3-6 young after an 18-day gestation period. Most of the Mice born late in the summer are not able to put on enough weight to survive hibernation.
