A American mink (Mustela vison) usually gives birth to around 4 babies.

Each of those little ones spend around 51 days as a fetus before they are released into the wild. Upon birth, they weight 8 grams (0.02 lbs) and measure 5 cm (0′ 2″). They are a member of the Mustelidae family (genus: Mustela). An adult American mink grows up to a size of 36.6 cm (1′ 3″).

They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.

The American mink (Neovison vison) is a semiaquatic species of mustelid native to North America, though human intervention has expanded its range to many parts of Europe and South America. Because of range expansion, the American mink is classed as a least-concern species by the IUCN. Since the extinction of the sea mink, the American mink is the only extant member of the genus Neovison. The American mink is a carnivore that feeds on rodents, fish, crustaceans, frogs, and birds. In its introduced range in Europe it has been classified as an invasive species linked to declines in European mink, Pyrenean desman, and water vole populations. It is the animal most frequently farmed for its fur, exceeding the silver fox, sable, marten, and skunk in economic importance.
