Can you kill stray animals or wild animals if they are damaging your property?

I wouldn't recommend killing the cats although I believe you can. If the humane society doesn't do anything about it the next time I would recommend trapping them then halling them off to the humane society your self. Note to self.,,if you do trap them be very careful in case any of them might are very angered/scared or have wringworms, rabbies, e.t.c.
