I grew up on the farm and we always had cats around, but I think that cats are like rabbits because they can multiply real fast so about twice a year my dad and I would have to go out and thin the herd. Last fathers day I bought him a 22 revolver, he was so excited because the cats had learned when he went outside with the rifle to run under the shed. Now when he goes outside he just puts it in his back pocket and pulls it when needed.
