Hi, my neighbour has 4 cats 2 of which act completely feral, one of those killed my young rabbit and together they are fighting every other cat in the neighbourhood. Literally ganging up on other cats. Yesterday they Injured my neighbours cat which could have been a lot worse if another neighbour didn't scare them off. The owners don't care, I told them about my rabbit and they offered to buy some cat repellant which I am still waiting for 2 months on. How do I report the owners/cats because this can't continue it's everyday and they are going to end up killing someone thing else?
