We could just get out b-b guns Kill the cats and small animals all at once.
I don't like other people's animals around my property, but they are really not doing any harm. Cats pretty much just get out of your way. (Exactly why animal control can't catch them.) It's not like my dog who would just lick you until you wanted to kill him! Dogs are different.
I guess what I'm saying is: cats don't really bother anything (unlike dogs might). I personally eat meat so the killing thing doesn't bother me.
