How many baby Muskrats are in a litter?

A Muskrat (Ondatra zibethicus) usually gives birth to around 6 babies.With 2 litters per year, that sums up to a yearly offspring of 12 babies.

Each of those little ones spend around 27 days as a fetus before they are released into the wild. Upon birth, they weight 22 grams (0.05 lbs) and measure 13.5 cm (0′ 6″). They are a member of the Muridae family (genus: Ondatra). An adult Muskrat grows up to a size of 27.7 cm (0′ 11″).

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 muskrat (Ondatra zibethicus), the only species in genus Ondatra and tribe ondatrini, is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans.The muskrat is the largest species in the subfamily Arvicolinae, which includes 142 other species of rodents, mostly voles and lemmings. Muskrats are referred to as “rats” in a general sense because they are medium-sized rodents with an adaptable lifestyle and an omnivorous diet. They are not, however, members of the genus Rattus.
