A couple months ago my cat's right ear started drooping, not the tip bending, but the entire ear just being held lower than the other. It is occasionally accompanied by the eye on the same side slightly squinting. At first I thought maybe it was a small stroke/paralysis, but then if you get her alert it perks up just fine and she has no weakness of motion on that side of the face.
She does not have fleas, and I am fairly certain it's not ear mites. There is no swelling, no rash, no scratching/itching or shaking of the head. There appears to be no discomfort though she is reluctant to let me look at it, nor is there any change in her behavior. Any ideas what might be going on?
