I had to deal with this myself for about 10 years until my road got cut off by a new highway about 15 years ago. It seems that everyone from "town" that wanted to "relocate" their sick, dying, pregnant or otherwise unwanted pets had decided that us folks outside the city limits would welcome them with open arms.
