Clumsy ripped a nail :(

[tfw]

So that stump of a toenail is turning white. Almost looks like it's going to one day fall out and never grow back. Anyone have this happen? It's not bothering her, she's her normal super active self, and climbing and playing is not affected whatsoever. And I'm sure she'll be fine if it falls out. But just wondering if this is the case - that it's dead.
