Bro have cat trap or not? I'm serious, neighbour's 7 cats keep coming into my property to shit. I want to trap it and put it at my fence next to his property to show him his cat had been trapped and want him to come claim them.
I suggest you give them poison cos there is just no way your neighbour can control his cats. Just feed them poison and let them die at your neighbour's house.

...and it works!!!!
