When you purchase from these artists, some of the proceeds benefit animal charities. Go to
http://www.etsy.com/treasury_list.php?room_id=60826 to support them and check out their shops!
P.S. You can buy as much as you want from any of these Etsy artists who donate to animal causes, including me, even if it's the whole shop! We'll be more than happy to just make more items :)
