Can you kill squirrel with an air rifle?

it really is a bad idea to eat your air rifle.perhaps you mean"where may i shoot a squirrel with my air rifle,and then eat the squirrel?" in which case ,a good idea would be to look for roadkill squirrels,then you would know there were squirrels in the area.i know they are regarded as a pest,but it is still bad to shoot a female with nursing young.give it some thought.........
