It is hard to guess what a Rock squirrel weights. But we have the answer:
An adult Rock squirrel (Spermophilus variegatus) on average weights 715 grams (1.58 lbs).
The Rock squirrel is from the family Sciuridae (genus: Spermophilus). It is usually born with about 7 grams (0.02 lbs). When reaching adult age, they grow up to 27.3 cm (0′ 11″). On average, Rock squirrels can have babies 1 times per year with a litter size of 4.
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 rock squirrel (Otospermophilus variegatus) is a species of rodent in the family Sciuridae and is native to Mexico and the southwestern United States, including southern Nevada, Utah, Colorado, Arizona, New Mexico, Western Texas and the panhandle of Oklahoma.
