How many babies does a Cactus mouse have at once? (litter size)

How many baby Cactus mouses are in a litter?

A Cactus mouse (Peromyscus eremicus) usually gives birth to around 2 babies.With 3 litters per year, that sums up to a yearly offspring of 6 babies.

Each of those little ones spend around 27 days as a fetus before they are released into the wild. Upon birth, they weight 2 grams (0 lbs) and measure 1.3 cm (0′ 1″). They are a member of the Muridae family (genus: Peromyscus). An adult Cactus mouse grows up to a size of 9.1 cm (0′ 4″).

To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The cactus mouse (Peromyscus eremicus) is a species of rodent in the family Cricetidae. It is one species of a closely related group of common mice often called deer mice. Cactus mice are small, between 18 and 40 g in weight. Females weigh slightly more than males and are significantly larger in body length, ear length, length of mandible, and bullar width of skull. Cactus mice can be identified by having naked soles on their hind feet and almost naked tails, which are usually the same length or longer than the animals’ body length. Their ears are nearly hairless, large, and membranous. Their fur is long and soft; coloration varies between subspecies and between different populations. Color of fur varies from ochre to cinnamon, with white ventral areas, and the sides and top of head slightly grayish. Females tend to be slightly paler in color than males, while juveniles appear more gray than their parents.
