My cat has scabs all around her head, neck and ears. The ones I'm most concerned with is on her ears they have bleeding where she scratches on them. I'm not sure if it is fleas causing this or what ... have seen some fleas on her and have also put some flea treatment on her to try to kill them, but it forced the fleas to migrate around her head and face. In all my years of owning cats I have never seen anything like this. What can I do for her?
