I'd be seriously unhappy if I lived on a small city lot and the neighbor added goats. They are loud. They stink, and they produce flies.
At my current house, I have a neighbor with goats, but we each have 2 acres and are zoned agricultural.. That is a huge difference. I like the neighbor and I don't mind the goats, but they produce an enormous number of flies and I am constantly buying fly traps to keep them under control.
If the wind is wrong, I smell goat, and I hear a lot of bleating, starting even before the sun comes up. Fine. I choose to live in the country and the country comes complete with farm animals. I expect it.
But people who buy those tiny little postage stamp size yards in the city don't want to live in the country, or else they would have purchased in the country to begin with.
It rains constantly in Eugene, so the yard with the goat would be a muddy mess. Not a nice thing to have next door. Of course, I'd never live in Eugene, anyway. They take "liberal" way beyond the point of "crazy".
