It is hard to guess what a House mouse weights. But we have the answer:
An adult House mouse (Mus musculus) on average weights 19 grams (0.04 lbs).
The House mouse is from the family Muridae (genus: Mus). It is usually born with about 1 grams (0 lbs). They can live for up to 6 years. When reaching adult age, they grow up to 6.1 cm (0′ 3″). On average, House mouses can have babies 4 times per year with a litter size of 5.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The house mouse (Mus musculus) is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and hairy tail. It is one of the most abundant species of the genus Mus. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity.The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002.
