It is hard to guess what a Oldfield mouse weights. But we have the answer:
An adult Oldfield mouse (Peromyscus polionotus) on average weights 14 grams (0.03 lbs).
The Oldfield mouse is from the family Muridae (genus: Peromyscus). It is usually born with about 1 grams (0 lbs). When reaching adult age, they grow up to 12.4 cm (0′ 5″). On average, Oldfield mouses can have babies 2 times per year with a litter size of 3.
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 oldfield mouse or beach mouse (Peromyscus polionotus) is a nocturnal species of rodent in the family Cricetidae. It is found in the southeastern United States on sandy beaches, in corn and cotton fields, and in hedge rows and open timber tracts. Coloration varies with geographic location; inland populations are generally fawn-colored, while coastal populations are lighter or white. The mouse eats seeds, fruits, and occasionally insects, and lives and raises its three to four young (at a time) in a simple burrow. Weaning occurs at 20–25 days, and females may mate at 30 days of age. Predators are those that prey on small mammals. One individual lived in captivity for about five years. The mouse is of least concern to conservationists because it is abundant and widespread, and no major threats exist for the species as a whole, but several subspecies with small distributions are endangered or even extinct.
