What's wrong with my kitties ear???

I just saw this today and I have no idea what's wrong. We just came from the vet a week ago and she was given a clean bill of health so I'm kind of worried especially since I won't be able to see her vet till next week. Any idea what it could be!?!

I'd get her back to the vet for a check up.  It could be anything from ringworm to a skin irritation, but whatever it is, it definitely needs to be checked by a vet.

Agreed. Definite vet visit and preferably soon.

Ouchie! I would get it looked at too just to be sure it isn't anything serious. On a lighter note, it could be that your kitten scratched herself on something. The other day I say a new scratch that was a little bloody on one of my boys, but it was just a sore from roughing around the house being a silly kitten. Since the picture you posed looks like quite a big sore I would get her in for a check up.
