Hadley keeps twitching one of her ears while she's sitting on her lap. It doesn't seem to be bothering her, no head tilt, no reaction to me touching it or looking at it. She seems otherwise healthy- bright, alert, active, good appetite, normal behaviors, etc. Her skin is fine...no hair loss, no flakes, and I can't think of a possible way that she could have been exposed to mites or anything else that would irritate the skin (she's been here for 2.5 months, no hay from outside, no time outside, etc.) Is it just a weird tic or could she have some sort of ear problem? I really hadn't noticed it before today.
