It is hard to guess what a Western mouse weights. But we have the answer:
An adult Western mouse (Pseudomys occidentalis) on average weights 34 grams (0.07 lbs).
The Western mouse is from the family Muridae (genus: Pseudomys). When reaching adult age, they grow up to 10.2 cm (0′ 5″). Usually, Western mouses have 3 babies per litter.
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 western mouse or walyadji refers to Pseudomys occidentalis, a species of rodent in the family Muridae. Once widespread across a larger range, it has become restricted to around ten reserves of remnant bushland in Southwest Australia and declared near threatened by extinction. They are small and robust mice that live in burrows in sandy soil, venturing out at night to forage in nearby area.
