I'm sitting in class right now so I'll add pictures to this when I get home this afternoon but I wanted to post this now while I'm thinking about it.
The past few weeks, KaCee's nose is slowly changing from the normal black color to a whitish/pinkish/gray color around the edges. It almost seems like it's chapped maybe from her licking herself?

It doesn't seem to be bothering her- she doesn't itch at it, she's not excessively licking, it doesn't bother her when I touch it.
Does anyone have any experience with this?
