Be sure that they are not Kangaroo Rats. They're protected by the Guv'ment, ya' know. I would grab six-pack of your favorite frosty beverage and a box of Aguila Colibri .22s. They are cheaper than buying a bb/pellet gun and just about as loud out of a shorter barrel single shot, lever, or pump. They are not powerful enough to cycle a semi-auto.(around 450 fps)........Nevermind, I notice that you live in city-limits.
