How many babies does a Hispid cotton rat have at once? (litter size)

How many baby Hispid cotton rats are in a litter?

A Hispid cotton rat (Sigmodon hispidus) usually gives birth to around 5 babies.With 2 litters per year, that sums up to a yearly offspring of 10 babies.

Each of those little ones spend around 27 days as a fetus before they are released into the wild. Upon birth, they weight 6 grams (0.01 lbs) and measure 1.6 cm (0′ 1″). They are a member of the Muridae family (genus: Sigmodon). An adult Hispid cotton rat grows up to a size of 16.7 cm (0′ 7″).

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 average litter size of a Hispid cotton rat is 5

The hispid cotton rat (Sigmodon hispidus) is a rodent species long thought to occur in parts of South America, Central America, and southern North America. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split this widely distributed species into three separate species (S. hispidus, S. toltecus, and S. hirsutus). The southern edge of the S. hispidus distribution is likely near the Rio Grande, where it meets the northern distribution of S. toltecus (formerly S. h. toltecus). The northern extent of S. hispidus distribution is to the Platte River in Nebraska and from Arizona to Virginia. Adult size is total length 202–340 mm (7.9–13 in); tail 87–122 mm (3.4-4.8 in), frequently broken or stubbed; hind foot 29–35 mm (1-1.3 in); ear 16–20 mm (0.6-0.9 in); mass 50-250 g (1.7-9 oz). They have been used as laboratory animals.
