How can i get a petition for my neighbors to move?

Well i live in a duplex with my mom, dad, and sister, my neighbor is a *****. Like, she would curse at us when we got off of the bus. Not only that but when we first moved in it was alot of cats, we're nice people so we feed them, one day she came out and said she was going to poison them, not only that bus out other neighbor is a cop, she had him up for something he didn't do, but nobody around this area likes her, we just really need her to leave. Somebody help .
