Hi
I have two cats. One of them: shake its head, lose fur around head and neck (but especially ears), ear pinna is covered by greyish "spots", she is very itchy, sometimes appear redness (pinna).
The other one: just hair lose, itchy skin, shake head.

Both of them had darkish discharge but after swab test( yeast infection was detected) we got ear drops and now it is clear.
We bought advocate and now one of our cats has stopped to scratch.
Please help us to diagnose it. Thanks in advance Teresa
