How many babies does a Roborovski dwarf hamster have at once? (litter size)

How many baby Roborovski dwarf hamsters are in a litter?

A Roborovski dwarf hamster (Phodopus roborovskii) usually gives birth to around 6 babies.

Each of those little ones spend around 21 days as a fetus before they are released into the wild. Upon birth, they weight 1 grams (0 lbs) and measure 3.3 cm (0′ 2″). They are a member of the Muridae family (genus: Phodopus). An adult Roborovski dwarf hamster grows up to a size of 7.2 cm (0′ 3″).

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 Roborovski dwarf hamster is 6

The Roborovski hamster (Phodopus roborovskii), also known as the desert hamster or Robo dwarf hamster, is the smallest of three species of hamster in the genus Phodopus, averaging under 2 centimetres (0.8 in) at birth and 4.5–5 centimetres (1.8–2.0 in) and 20–25 grams (0.71–0.88 oz) during adulthood. Distinguishing characteristics of the Roborovskis are eyebrow-like white spots and the lack of any dorsal stripe (found on the other members of the genus Phodopus). The average lifespan for the Roborovski hamster is 2-3 years, though this is dependent on living conditions (extremes being four years in captivity and two in the wild). Roborovskis are known for their speed and have been said to run an equivalent of four human marathons each night on average.
