What is the maximal age a Bush rat reaches?
An adult Bush rat (Rattus fuscipes) usually gets as old as 3.42 years.
Bush rats are around 22 days in the womb of their mother. When born, they weight 4 grams (0.01 lbs) and measure 19.1 cm (0′ 8″). As a member of the Muridae family (genus: Rattus), a Bush rat caries out around 4 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 15.8 cm (0′ 7″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
