So, we have developed quite a rat problem. I would see the occasional mouse/rat before, but our neighbor has moved in some cows, and feeds them sileage (?) and other stuff, and ever since, the rats have gotten worse and worse. I can't control the neighbors' cow feeding, and I really think that's where the problem is coming from. I really want to get rid of the rats. Here is my problem. I have a cute little rabbit that roams freely around my yard. He/she showed up around December, and I figure if it managed to survive this long on its' own, it deserves to be free, so I hesitate to catch it. I don't want it getting into the poison, traps, etc. I also worry about my chickens getting into traps or poison. I know it wouldn't completely fix things, but if I could shoot any rat I saw, I'd feel better about it. But, I live about 3 blocks from a police station, and have neighbors fairly close. The closest neighbors wouldn't mind at all (they'd probably even lend me the gun), but the further away neighbors COULD possibly call the police if they heard shots. So, I hesitate to use a .22 or something along that line because of the noise. BB guns are really quiet, and I think I would never get caught shooting that. But, I don't want to bother buying one if they won't actually kill them. So, BB gun or silencer for my 22?
