How many baby Hooper’s mouses are in a litter?

A Hooper’s mouse (Peromyscus hooperi) usually gives birth to around 3 babies.

Each of those little ones spend around 33 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 Hooper’s mouse grows up to a size of 9.8 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.

Hooper’s mouse (Peromyscus hooperi) is a species of rodent in the family Cricetidae. It is the only member of the Peromyscus hooperi species group, and is found only in Mexico. The species is named for Emmett Hooper, a researcher into the taxonomy of the genus Peromyscus.
