It is hard to guess what a California mouse weights. But we have the answer:
An adult California mouse (Peromyscus californicus) on average weights 42 grams (0.09 lbs).
The California mouse is from the family Muridae (genus: Peromyscus). It is usually born with about 4 grams (0.01 lbs). When reaching adult age, they grow up to 11.6 cm (0′ 5″). On average, California mouses can have babies 4 times per year with a litter size of 1.
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 California mouse (Peromyscus californicus) is a species of rodent in the subfamily Neotominae in the family Cricetidae. It is the only species in the Peromyscus californicus species group. It is found in northwestern Mexico and central to southern California. It is the largest Peromyscus species in the United States.While most rodents are polygamous, the California mouse is monogamous and forms pair bonds, making it a model organism for researchers studying the genetics and neurobiology of partner fidelity and paternal care.
