I am getting one I wanted to tell people about it now because I think it is totally awesome wingedwolf_2004 is using his furry art to help children in need around the world. I would love to see more artists in the fandom doing this. For Christmas I am thinking about doing something similar with World Wildlife Fund Adopt an animal campaign and I will be adopting animals in honor of my closest friends in the fandom.
If any other artists want to do something like this and you are looking for a good campaign to support, feel free to comment or email me and I will be more than happy to point you to a really great cause.
So get a badge from Wingedwolf. They're awesome badges, they're very resonably priced, and your money is going to a great cause.
