I kill them all the time in my back yard. Ill be out shooting my longbows and when a squirrel comes by, Ill smack it with a blunt. I wouldnt mind the guys hanging out around my place, except they chew everthing up. Ive had to rewire my workshop, office, and big shop because of the bas%Q$ds. Not to mention they chew up my boat covers, camper, lawn furniture etc.. They ruin everything around my place.
As for biggest, they are all about the same size.
