I can't bring myself to click on the link and read her story. I know it's going to make me want to cry...
I remember watching a show where it was about animals with "disabilities". The narrator said the animals don't really realize that there's anything "wrong" with them and it's more of the human's take on them.
I also remember seeing a 3 legged fox at a small petting zoo. I saw him running around with his mates. And you know what? He was the FASTEST among all of them!
I think if you can afford the time/money on adding a new member, I would think this is a sign.
She's absolutely adorable.
