For any one that has a child in the house and has a gun they should have a gun safe. Or at least trigger locks. I grew up with guns and learned to use them early in life. Thanks to my daughter I will have to start locking my guns up again when the new grand baby comes here. With the other 4 grand children, ages 8 to 16, they all have thier own guns here. Each of them know how to use them. Not only have I taught them gun safety, they all have passed both the police and fish & game safet courses. I don't worry about weasles here, just bear and mountian lions. A little different critter. Not wanting to start any battles, but there is no differance between children be it natural or foster. Without the proper training they should NOT be around any gun. I have NEVER known a gun to kill anything unless it was in the hands or a human. Like I have stated before, I go more for over kill and I am never more then a few steps from a fully loaded gun. Most of the time I have one on my person. And doing what you do with foster children you should get a medal or something. Sorry I am not a lot closer or I would take care of the weasle for you.
