Cry for Help

I am a in bit of a quandry. Just before Christmas my elderly next door neighbour had her daughter move in with her. Now Poppy (real name) is 84 so her daughter must be about 60 and what a pain she has turned out to be. Not only did she move in but she brought nine (9) cats with her. It looks as if she picks up strays etc. Anyway, the gardens around here are reasonable enough but not to support 9 cats so of course they are doing their business in everybody else's gardens including mine. They have already dug up the flower beds and it's getting to be a bit of a pain. Anybody got any ideas as to how we can resolve this. We did try to speak to the daughter but she was quite rude and then walked off so no joy there.

RSPCA nor the council want to know as they say provided the cats are not ill treated or there is no big smell getting into our house they have no power to act. I'm thinking of getting one of those water guns. I don't want to hurt the cats but we also have a cat, a rather small on who is now being bullied by these much bigger males ans hardly goes out anymore.

Suggestions welcome guys
