I also think it still sounds like earmites! There is a one dose treatment that you can get. It's much easier than having to clean and re-medicate for several days. It's a bit expensive, but well worth it to have it gone in one treatment! Now let me see if I can remember what it is called! *sigh*

Here it is ... it's called Acarexx!
