It is hard to guess what a Long-haired rat weights. But we have the answer:
An adult Long-haired rat (Rattus villosissimus) on average weights 221 grams (0.49 lbs).
The Long-haired rat is from the family Muridae (genus: Rattus). When reaching adult age, they grow up to 18.6 cm (0′ 8″).
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 long-haired rat (Rattus villosissimus), is a species of rodent in the family Muridae which is native to Australia. The long-haired rat is well known for its population eruptions over vast areas of Australia which is the basis of its alternative common name, the plague rat. Most of the research on the long-haired rat has been conducted during times of massive population fluctuations and therefore little is known about their biology in a non-eruptive period.
