I am assuming you live in an urban area- not somewhere that the deer and the antelope play. So, if I understand the question- you enable a cat, by feeding-caring- etc, to wander through the neighborhood and damage other's property. Do you feed your cat outside- are you feeding and attracting more strays?? If you heard about it from one neighbor, more than likely several others are thinking the same thing. It is the owners responsiblity to control their animals. Keep it inside, get an electric fence- which is what our neighbors did and it helped some. To hide behind the excuse that that is what cats do is foolish. The same argument could be made by a neighbor raising attack dogs- don't get upset if they attack, it is not my fault, that is what they do. Be glad your neighbor doesn't get a cow and let is crap all over your garage- that is what they do as well. I assume your cat wears a collar with id and tags proving its shots are up to date, if not in my book it is a stray. I would control my cat- or not be surprised if it ends up 3 cities away- heck you said you did the same thing.
Be a good neighbor- cats belong inside.
