It is hard to guess what a Western gray squirrel weights. But we have the answer:
An adult Western gray squirrel (Sciurus griseus) on average weights 704 grams (1.55 lbs).
The Western gray squirrel is from the family Sciuridae (genus: Sciurus). When reaching adult age, they grow up to 29.4 cm (1′ 0″). On average, Western gray squirrels can have babies 1 times per year with a litter size of 2.
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 western gray squirrel (Sciurus griseus) is an arboreal rodent found along the western coast of the United States and Mexico. It is a tree squirrel.In some places, this species has also been known as the silver-gray squirrel, the California gray squirrel, the Oregon gray squirrel, the Columbian gray squirrel and the banner-tail. There are three geographical subspecies: Sciurus griseus griseus (central Washington to the western Sierra Nevada in central California); S. g. nigripes (from south of San Francisco Bay to San Luis Obispo County, California); and S. g. anthonyi (which ranges from San Luis Obispo to northern Baja California).
