Facebook is running a fun when you sign up for your birthday. They give you $5 to kick off the campaign, they collect the money and see the charity gives it.
I chose the Blind Cat and Rescue Shelter, which I have supported for a long time.
There is another way you can help this shelter -- when you buy nearly anything on Amazon.comyou can create a special URL called SMILE. Each time you buy from Amazon a percentage will go toward your charity.
