A Desert mouse (Pseudomys desertor) usually gives birth to around 3 babies.

Each of those little ones spend around 28 days as a fetus before they are released into the wild. Upon birth, they weight 4 grams (0.01 lbs) and measure 3.3 cm (0′ 2″). They are a member of the Muridae family (genus: Pseudomys). An adult Desert mouse grows up to a size of 8.8 cm (0′ 4″).

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