It is hard to guess what a Stein’s rat weights. But we have the answer:
An adult Stein’s rat (Rattus steini) on average weights 151 grams (0.33 lbs).
The Stein’s rat is from the family Muridae (genus: Rattus). When reaching adult age, they grow up to 17.1 cm (0′ 7″). Usually, Stein’s rats 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.
Stein’s rat (Rattus steini), also known as the small spiny rat, is a species of rodent in the family Muridae. It is found in West Papua, Indonesia and Papua New Guinea.
