deer mice age
Deer mice become sexually mature at five or six weeks of age. A female deer mouse can have up to eleven litters of one to nine young in a year. The average gestation time for each litter is 24 days.The litter size increases until the fifth or sixth litter and then declines.The young are tiny (1 or 2 grams) at birth.eer mice can live up to five years in captivity but probably only live about a year in the wild. This shorter natural life span is primarily due to the very large number of predators that take and consume deer mice.
