We have a neighbor who pretty much neglects his cat. The cat is outside rain, snow or shine. Last winter, the poor thing had nowhere to go when the temps dropped well below freezing. I told the neighbor he should keep the cat indoors, but my remark fell on deaf ear. So I built him a temporary shelter to at least keep him out of the wind and snow (we couldn't and still can't bring him indoors for a variety of reasons). Well, he liked it so much that he has made our back porch his. During the summer, I upgraded his shelter and now that nights are getting cooler again, he has moved into his new house (solid cedar siding, aluminum roofing, and faux fur mattress):
