Check out Wildcat Woods vintage Treasures: http://wildcatwoodsvintagetreasures.blogspot.com/.
This family has rescued and cares for feral cats. They even moved ferals to another town with them so the cats they previously TNR'd would be forever cared for. They have some great vintage items for sale including jewerly, books, clothing, housewares, home decor items, etc. All the proceeds go to care for the cats to help pay for food and medical care. And they have quite a few kitties with chronic health issues.
Please check out the site and hopefully you'll see something you can't do without -- because again, all the money goes to care for the cats.
