Take sleeping pills, grind down, sprinkle on tuna, leave outside in a place where neighbor can't see.
Cats will eat the tuna, ingest the ground up pills, OD and get really sleepy. Cats don't want to sleep somewhere unsafe though, so they will go back to the neighbor that fed them, fall asleep in his driveway and die there.
Now your neighbor got ten dead cats in his driveway, and everybody knows who regularly feeds cats in the neighborhood. Your neighbor will take all the blame.
You could also visit that one air rifle thread, pick a rifle and shoot the fuckers. As long as you dispose of the bodies in a way that thee authorities won't find the round of your air rifle inside them place bait in your backyard, wait, kill cat, collect body, put in garbage bag, dumpster there won't be any lead to you.
Another method would be ultrasonic poisoned cat nip.
Cat nip is a plant, that naturally grows in many areas around the globe. You can buy it in any floral store IIRC. Rub some poisonous plant of your choice (Digitalis, or Foxgloves are common in Europe, wear gloves when handling, dispose gloves after handling) on the leaves. Cats will come, rub against the plant, chew on it, ingest some of the poisons. Not only that, but the poisons will stick to their fur. When they clean themselves afterwards they will ingest even more.
Noone will look into it too much. They will just assume that the cats poisoned themselves on some wild foxglove plant or whatever.
Or, you know, ask your fucking neighbor to stop feeding the cats.
