Squirrels! This is North America and we have squirrels.
According to Wild Oakland, "Eastern fox squirrels (Sciurus niger), Western grays (Sciurus griseus), Eastern grays (Sciurus carolinensis), and California ground squirrels (Otospermophilus beecheyi)" are the main kinds of squirrels that we have in the Bay Area. "Around the East Bay, the Eastern fox squirrels are going to be the type you see around, while the Eastern grey is the predominant squirrel in San Francisco." [source]
