Attacked a human, did he have blood dripping off his fangs, sorry a baby squirrel does not have fangs, ok, the baby vampire squirrel attacks, is that better. Call swat, more firepower is needed here.
Dang, I forgot the sun would have got the vampire squirrel in a minute. But then he could have been one of those baby vampire zombie squirrels, in which case they would have required a swat tank.
