An aggressive squirrel pounced on a 4-year-old boy in an attack last week in Cuesta Park in Mountain View, Calif. The attack happened as the boy's mother unwrapped a muffin during a picnic. The boy had to get rabies shot after the attack. He is still getting the shots. The attack is not the first one reported at the park. Mountain View Community Services Director David Muela said that as many as six people have been bitten or scratched by squirrels since May, and that the attacks have become more ferocious in the last month.

In response to attacks, the city of Mountain View has announced it plans to start trapping and killing the aggressive tree squirrels. Over the next three weeks, park workers will set tube-like traps in the trees of Cuesta Park and euthanize captured squirrels "in a humane way," said David Muela, Mountain View's community services director. Ironically, efforts to curb the behavior may have exacerbated the squirrels' aggressive tendencies, Muela said.

This summer, the city installed new trash receptacles featuring metal tops with a latch that makes it nearly impossible for an animal to rummage through the can in search of food. Increased park ranger patrols and flier distributions cautioning against feeding the animals might have further cut the squirrels' food supply, prompting them to act more assertively in their quest for food.
