That's why you use a pellet gun from inside the house. Whatever noise there is is contained in the house...and the neighbors can't see what you're doing. A "wrist rocket" slingshot is also good. But a load of #6 shot is best of all.

I have a box of .22LR C.I.L. ammo that's never been used, if you can figure a way to obtain it. Postal services don't like stuff like that to be mailed and it seems kinda silly to go through all the paperwork required to ship it legally. This is the genuine Canuck article, too.
